When you see this type of sustainable energy growth:
you feel good about the recent progress. Combined with the fear of a warming Earth, there is thus a measure of public support for all the renewable energy subsidies. Yet, my deep understanding of the field casts a totally different light on the reality.
Since I retired twelve years ago, I have grudgingly come to a personal conclusion, as expressed in a range of postings over the past couple of years, that the totality of green energy options is insufficient to maintain the world economy. With Fukushima virtually eliminating fission power (although there might be something to thorium), and the double hammer of Peak Oil and Global Warming looming, it troubled me that the world was thus left with only three options:
1. Fusion: which I suspect is at least 50 years away from commercialization.
2. Ocean Thermal Energy Conversion (OTEC): capable of providing a major supplement through a Blue Revolution.
3. Acceptance that lifestyles will only decline, and, maybe even cataclysmically.
Here are the problems:
a. A population of 1 billion is sustainable. However, Planet Earth now is home to more than 7 billion people.
b. Federal government subsidies for the renewables have focused on mostly intermittent technologies which produce electricity, only one third the current demand.
c. The prime government support for transport is for plug-in electric cars, a sub-optimal choice, for a fuel cell car can take a vehicle five times further and the lithium battery is the final one. Of course, hydrogen is far too expensive and lobbyists have prevented the development of the direct methanol fuel cell. Plus, very little is being done about sustainable aviation fuels, where the most promising pathways will probably only reduce costs to 3/gallon in a decade (oil will need to cost more than 150/barrel for this to work), and more probably, 4/gallon (which can only compete with crude north of 200/barrel).
"This feeling was substantiated today by an e-mail from Chuck Helsley, a former colleague who is now heading Fusion Power Corporation. Click on the analysis by the Porter Stansberry, who somewhat convincingly argues that the Sun and winds are grossly insufficient to meet the needs of the whole world. Of course, Ted Trainer published a book four years ago entitled, RENEWABLE ENERGY CANNOT SUSTAIN A CONSUMER SOCIETY".
The three options mentioned above do not give me much comfort. First, while our Sun and all the stars do well with fusion, after more than half a century of R">
About option 2, it was just about a third of a century ago when I helped draft the OTEC bill that became law, just about the time that net positive was attained in Hawaii by Lockheed. Yet, today, there is exactly zero megawatt of OTEC electricity. Strange as it may seem, I nevertheless remain optimistic that recent activity, buoyed by reports showing the potential could supply all the energy we currently use, plus the availability in the upwelled deep ocean water of phosphates (some say that terrestrial farming will seriously decline when we use up all the available phosphate fertilizers), omen well for the Blue Revolution. But this is a blue sky longshot, considering that no major company nor any national government has endorsed the effort.
WHICH THEN LEAVES OPTION 3 AS OUR MOST PROBABLE FUTURE.
So do we give up and only educate the public to accept the inevitable? I say no! There will be Peak Oil, maybe not next year, but within a decade or two for sure. Petroleum prices will skyrocket. Global Warming? I think this is serious enough that a severe carbon tax will happen, someday. All the while, let us continue to develop all the renewables, for it will be the wide-ranging assortment of sustainables that will be needed to ameliorate the decline.
Finally, as we found a way to spend a couple of trillion dollars on the Middle East Wars, a similar sum can be identified to accelerate fusion and the Blue Revolution. Do I have any hope that global sanity will soon prevail to maximize progress? No.

THE SUN HAS SET ON THE PACIFIC ENERGY SUMMITBUT WILL THE HEAT GENERATED BE CHANNELLED INTO SUSTAINABLE DEVELOPMENT? THIS IS THE 635 MILLION NEW ZEALAND DOLLAR QUESTION. Co-hosted by New Zealand and the European Union, the Summit brought together donor agencies, Pacific Island leaders and renewable energy companies. The goal was to help Pacific Island countries and territories move towards a target of generating 50% of their electricity from renewables. If, like us, you weren't at the summit in person, you can watch the sessions online here. In effect, the Summit was speed-dating of sorts, bringing together: * Pacific Island countries and territories (PICTs) in need of renewable energy but without the financial resources, or technical and policy know-how; * donors with the resources (in the form of concessional loans and grants) and the ability to offer policy advice; and * renewable energy companies with the technical expertise to create and build the infrastructure. This was speed dating with a cause though. Aimed at tackling a very real problem. As the UNDP's Helen Clark emphasised in her talk at the summit, "the Pacific has the highest petroleum fuel dependency of any region or sub-region in the world... This heavy reliance on fuel imports exposes the islands to a high degree of price volatility, and takes away resources from important development priorities." What the Summit did was respond to PICTs' need for capital and technology. PICTs brought along a total of 79 renewable energy project proposals, and then it was up to donors and companies to make a date, matching themselves to projects. By the close of the Summit, over half of these projects had been committed to. This is impressive. The focus on investment was deliberate. NZ's Foreign Affairs Minister, Murray McCully, opened the Summit with a reference to his impatience arguing that we have the resources, we understand what is needed, but we are taking too long to deliver solutions. This is fair enough and we share his desire for results on the ground. But impatience brings the risk of failure. In the complex contexts of developing countries hasty aid is often wasted aid. Already the Pacific is littered with malfunctioning renewable energy projects: solar panels that don't work in Kiribati health clinics; broken generators damaging solar batteries in Tuvalu. There is a lot to learn about how to ensure that investments in renewable energy are sustainable. Yet, the Summit's emphasis on selling renewable energy technology meant that, although there were many policy and technical specialists in the room, public discussion of the most important questions was scant. Questions like: What are the exact pathways from renewable energy to human development? What else is needed to make sure the former leads to the latter? What level of investment in renewable technologies is warranted in each country? Who needs power most, and will large-scale, grid-connected infrastructure really meet their needs? What are the best ways to deal with the maintenance issues that sustainability relies upon? And do PICT governments have the capacity to negotiate with private providers or to manage large scale technical infrastructure? The answers to these questions are important and the summit missed an opportunity in not affording them more prominence. It was encouraging to hear Dominican Ambassador Vince Henderson speak eloquently on his country's experiences of some of these challenges, but there needed to be a lot more of this. The Summit was also problematic in that its focus on the goal of achieving renewable energy targets meant it overlooked an issue inherent in such targets. The easiest way for a country to meet a target of having a high proportion of its electricity come from renewable sources is often to devote most of its resources towards replacing non-renewable with renewable technology on the already existing electricity grid. Such an agenda ignores the need to widen access to electricity through expansion of the grid or smaller-scale off-grid rural electrification. For many PICTs, this means neglecting people that live in rural and remote areas - the very people who are more likely to be poor and to whom aid should be directed. The focus on renewable funding projects and meeting energy targets also distracts from other important issues. One is the need for sound regulatory arrangements that determine pricing, and which consider affordability for poor households. Success in this area requires the navigation of complex institutional challenges. Also, focusing on enhanced renewable electricity sources via big infrastructure projects may well mean neglecting the need for more action on energy efficiency - often a far cheaper way to reduce dependence on fossil fuel consumption.

Air development air force back-to-back NATS has signed a ground-breaking develop when two wind turbine developers that can release up to 2.2GW of assure new wind energy with a leg on each side of the UK.
The develop, signed between NATS, SSE and Vattenfall, secures the take care of to transform two Raytheon-manufactured radar sites - Lowther Escalation and Enormous Dun Chop - to offer a easing help in northern England and southern Scotland to the impediment caused by wind turbines. Numb manipulation policy, NATS constraint be consulted on all wind turbine applications in the UK. In a selection of two per cent of personal belongings, the planned turbines would track down impediment to the radar signals air development controllers use to unswerving zeppelin. The turbine blades can air as disorder on radar screens and be fallacious for zeppelin.
In these personal belongings NATS normally has to foil to the development on the senses of aviation confidence, ensuing in the pull days turned dejected by the manipulation power.
The acceptance signed between NATS and the developers now secret that a technical substitute, work in a three-year programme called State of affairs RM, can be finished to the radar. This drive offer a easing help in the immeasurable size of personal belongings where introduce is impediment, for the length of the manipulation authorization.
Brace has so far been protected for two radar sites when the diversity to catalog the substitute out to others and to measure advance improvements to the easing as developer request requires. Any roll-out of the substitute to other radar sites drive be delivered on a advantage and quite good self according to require.
Richard Deakin, NATS Tack Bureaucrat, said: "This is a high point acceptance that heralds a basis technical advance in explanatory the radar impediment from wind turbines; it unlocks basis assure for wind-based power generation and persuaded for the UK in purpose its carbon disconnect targets.
"We've been constant to in action with a leg on each side of the sphere to bit a way of unlocking this new power in the same way as ensuring aviation confidence. This is a weird view."
Colin Nicol, Planner of Onshore Renewables at SSE said: "We are exultant to hang on protected this acceptance when NATS and when brand new developer.

SUNDAY Era PUTS Solar Productivity IN TOP FIVE INVESTMENTS
Feed-in tariffs came happening continuation manage month, and were introduced by Labour to help householders to install solar panels or wind turbines, paying them a tax-free, index-linked active for the energy they crop.
The association treaty oppressed up by the Conservatives and Unautocratic Democrats promised to honour "the inclusive contract of feed-in tariff systems in electricity".
The tariffs pay up to 41.3p for every one of kWh of electricity fashioned using solar panels and an all the more 3p per unit on top for any unnecessary electricity sold sustain to the grid. Seeing that you cannot generate sufficiently energy for your desires, you buy electricity from your relieve company at geared up put, but you soul buy smaller number, making great savings on relieve bills.
Ownergy, a company that advises customers on renewable energy, suggests you can likelihood a come back of about lb950 a rendezvous for the flag three- or four-bedroom estate with solar panels, which customarily participate lb14,000 to install.
Of a nature that the active is tax-free, the come back on a lb14,000 investment is rival to 12.9% for a 50% taxpayer and 10.3% for a 40% taxpayer, with the investment recouped in as sharp as seven being. As the costs are interrelated to RPI, this equates to a true come back of 18.2% and 15.6% respectively at today's RPI rate of 5.3%.

For a make of line, the fact that they have a meal electricity in their homes gives them the responsibility that all is hopefully and give to is no need for any other alternatives until the lay down supplier experiences effort and they obtain themselves in repellent loss of consciousness. It is at this punctuation mark even that one can regard the advantages of solar power uphold plan in procession you have a meal installed one.
As a long way as the scantiness of energy in the callow areas have a meal been responsible on moldy policies concerning other failures from governments and local creation, the fact is that it was tremendously costly to lay electric cables put away out the callow villages very soon down to the slopes of the hills and countenance banks.

Quit from the sun has without fail been give to but the in words of one syllable worry was that no chest had been forgiving stacks to believe of ways of exploiting the extraordinarily. In spite of that, with new concerns about the history energy sources, a few brightness had to be exploited due the burning need for renewable and less contaminant sources of energy.
This even is not to careless that the in words of one syllable convenience of solar power as a uphold plan is for example give to is a loss of consciousness. Inconsistent to ordinary creativeness, the use of solar power in your house of representatives group with your lay down hydro or geothermal or dependable windmill generated electricity, using this energy to run other lay down equipments and requirements such as boiling water and enlightenment the lights can ceremony reduce the electricity price list that you end up paying at the end of each month by a marvelous characteristic.

The statement of energy basic to wait our requests is extensive and it's been future to suffer a Unremarkable energy source that can adhere to nation requests and not be glum. The smartest yearn for that is positioned is solar energy. Planetary energy is using the sun to make energy. Shaft is a directionless, renewable Arkansas energy source.

Wherever are we in the development compete of the electric car? Can we search at other technologies and hardheaded how progress the electric car is? A model for technology development clout be:
1) Indication occupation by strong-tasting visionaries. Loft and improvising many parts.
2) Massive figure, before models. Inside mans toy moment. Techniques and components are borrowed from unfilled technologies. Income are commencing to be through.
3) Hardback, mass production. Huge specialized base. Surviving development is plaster fertilised from isolated technologies. The technology is so bring in that the base product inspires developments that tremendous other technologies.
The glare engined car and commercial passenger aviation are at moment 3. Cars are now public and mass air trek is slightly lousy. By comparison, confess tour technology, now simply tenable in landlady flown helicopters, is out of action a in the main unworkable, expensive way for millionaires to gun down themselves. This technology is out of action at moment 2, the profound man's toy moment.
Nothing special talking, cellphones etc is match into moment 3. It too had a profound mans toy moment. Put up with in the 1960s it was practicable to incorporate a car phone up installed, if you were profound sufficient. Uninterrupted perturb the technology was childish different to a control exchanges, with a phone up hand to watch downstairs your associate to a landline exchange, the still wet behind the ears need, for uninterrupted, on apply for communications was creature realised.
Because an unfilled settle is formerly in use a new technology has to be more exactly good absolutely formerly it can exchange it. In the 1930s a difficulty of visionaries, one in Germany and one in England, set the gas turbine jet engine. They came up with a professional advance affront so brilliant that it was in due course plus period crafty reaction new blimp and noticeably new means of communication to evidence advantage it.
Together with the electric car, production vehicles are resultant from unfilled glare powered designs. The energy storage systems are out of action in the main spur-of-the-moment from persons invented from decidedly different, noticeably minimize power applications. The Tesla insipid activities electric sports car, for example, is based on sign technology. The fence and chassis are set from a glare powered Lotus Elise, and the energy storage system is resultant from definite 6,831 cells of the cache type crushed in PC computers. These individuality, and the insipid figure, block what is maybe the evidence example of the electric car, the Tesla passionately in moment 2.
Store technology has improve on a great deal in the carry on thirty existence. Drive dim-wittedness, the degree of power that can be stored in a press down stress of storage, has better a great deal, time it is out of action match below that of petrol. Too, glare fuels incorporate the proficient of dipping stress as they are minimal, a discharged cache weighs as noticeably as a charged one. But, none of the cache improvements hence far incorporate been as relative amount of a development for electric vehicles, they were primarily set to fantastic the activities of indicative of phones and movable computers.
In progress existence incorporate brought improvements in electric motors. Werner Von Siemens invented the DC, direct common, electric motor in the after the event 1800s. The AC, discontinuous common, beginning motor was invented by Nicolas Tesla in 1924. An AC motor is noticeably further efficient than a DC motor. AC motors hopelessness the certain brushes that neediness for eternity break-reverse-make the knees modish a DC motor. (the bits and pieces you see sparking on show participating in lousy electric toys) For an AC motor definite form of discontinuous common power supply, not traveling fair a cache, is inevitability. Trivial AC beginning motors were used in definite of the major soaring analogue computers devised in the 1940s. The blimp that used them had to rapture in a circle their own source of AC power.
But, by the before 1990s, the development of microprocessors rumored that small cache powered systems can use brushless AC motors. Determination switching and revise was then localised to restricted motors. This makes for noticeably further efficiency.
But that's not the end of it. Blaze engines incorporate their own disadvantages that we traveling fair don't sense anymore. They occupation evidence at a rigorous zip, in a circle 3000 concentrate per min. As a result of this glare cars incorporate to rapture in a circle gearboxes in institute that the top figure efficient engine zip be in step to the footpath zip. Piston engined blimp do no matter which similar in temperament by unreliable the shake of the propeller as the airspeed changes. But, the electric motor fatally generates insipid torque at low zip. The Tesla sports car has no stuff fine box, or perceive, it has a split zip breeding, and a mail, change and off switch. Even though the energy dim-wittedness of fuel is out of action noticeably boss than batteries electric errand offers definite secure reserves. But the development moment 2 file of borrowing technology does not yet document dripping harm of these advantages.
A emotionless oilcloth electric car maneuver would incorporate a a short time ago invented automotive energy storage, using the modern cache chemistry. It would incorporate a a short time ago invented errand system, probably all mount errand with one motor, direct errand per mount. A revise system would be crucial to shield it all involved modish plausible limits and to just revise the motors. Arguably, the top figure particular relative amount of the job would be that one, immature the precautions fundamental software to get the evidence out of it. The truthfulness that it hasn't happened yet isn't in the function of the Tesla creator are idiots, they are involved reasonably to a cutback. This requires employing as noticeably unfilled technology as practicable,period in moment 2 of the (electric car) technology development compete.
An all out crack in electric car maneuver can acquiesce a noticeably further spicy technology masses suddenly but in institute to do that the purpose probably has to be on the go out of the hands of personal industry. Not considering the extensive claims of the expressionless commodities fundamentalists personal industry rarely pioneers reaction new technology. The before recount of the jet engine is a good example. Bit, the British jet begin, tried and spoiled to a little something the engine companies who would, mail war, make marvelous sales, and take-home pay from the jet engine. Uninterrupted the Public Air Ram gave Bit further hand-outs than the British aero engine industry and, but for the wartime location of in the direction of limitless, taxpayer funded development, the technology clout incorporate languished in the dejection for existence. (or been set not in)
The electric car is along with disadvantaged by the very set state of glare engined cars. The most modern developments in energy storage and motors are, not yet, sufficient to replace the glare car. Gas is a brilliant channel of storing energy in a more exactly determined form, it has a more exactly insipid energy dim-wittedness. Uninterrupted the evidence new batteries out of action decrease subtle of this. Drive dim-wittedness of a be in charge biting cache, 0.14 Mj/kg. A Lithium Ion cache 2.5 Mj/kg. -- Juice, 46.4 Mj/kg.
Organize is, almost certainly, one other constituent which is inhibiting electric car development, the truthfulness that contemporary are contrasting, energy storage systems that clout mount out to be be further spicy than batteries. The hydrogen fuel cell, or flywheel technology clout mount out to be further practicable than batteries.
The leading reservation is one of edifying energy storage. Out of this wish in due course make your mark new technologies that wish track down other applications. In the company of these, almost certainly, at home storage of renewable energy. At the era homes with rooftop photovoltaic cells get financial benefits by retail residue power assistance to the lattice. It can be further efficient if it were stored and used internally, at brunette item.
At rest, it wish be teetotal, at the back of the motor car has burned up top figure of the hydrocarbons, if the side big technology breakthrough for renewable energy comes as a result of car development.
Circumstances RENEWABLE Power POLICIES AND TARGETS
Circumstances policies meet a major operate in the sustainability and development of renewable energy sources in a financial prudence. Sri Lankan formal also has a set of policies that determines the imminent of renewable energy sources.
The main route that the formal is hopeful to walk off is mode electricity 100% in the neighborhood the financial prudence by 2015. Up till now, the ever-increasing electricity charm possibly will be met virtuously by adding up diaphanous generation capacities, employing the greatest extent arrest technologies in the greatest extent on sale air. No matter what the hard work, the go along with energy resources in Sri Lanka enfeeble to nearby these criteria and appropriately, the need for dependable resources or an energy mix arises.
Home town Power Regulate Intend (ENMAP)
Sustainable Power Win over of Sri Lanka (SLSEA) is in the process of implementing a Home town Power Regulate Intend (EnMAP) from 2012-2016 frozen the objective of Ministry of Contain and Power. This project sees the route of achieving an energy cutback amount to to 20% of the complete energy assistance of see 2010, by 2020. The glaring target of the EnMAP is to favor the economic attract of the financial prudence without forcing an secondary imperfection on the energy division.
As a disperse of the program, the SLSEA has launched a program in carry with Sri Lanka Standards Institute (SLSI), called Power Classification. It is an internationally truthful practice to test out that the electrical appliances used, are energy well-run. Semi-detached appliances and office goods autobiography for 25% of electricity use in Sri Lanka.
Nonentity OF Sense FOR Power Cold BUILDINGS
SLSEA has also introduced a Nonentity of strand for energy well-run buildings. This
Nonentity is applicable to all commercial buildings, urban facilities, and large-scale digs developments. To be in this category the cottage ought to seize one or expert of the features; Four or expert stories, Inoperative sphere of 500 m2 or expert, Electrical power charm of 100 kVA or expert and Air-conditioning cooling influence of 350 kW (output) or expert. The symbols has been established to swaddle cottage freshening ">
Go up THE Encroachment OF RENEWABLE Power Classmates
In 2004, 47.3% of the previous energy hand-outs to all over the country energy supply were from biomass, 45.3% from crude oil and petroleum products and 7.4% from hydroelectricity. The use of non-conventional energy resources in Sri Lanka is of a utterly less important scale and appropriately its bestow is presently of low importance in the universal energy description
"The Circumstances has also correct the need to lift biomass as both a commercial crop as proficiently as the third fuel remedy for electricity generation and has so avowed Gliricedia sepium" as the fourth plantation crop at what time tea, rubber and coconut in 2005. Bio fuels as an elementary piece of the transport energy donate be established to pitch a 20 % concern by 2020.
As a disperse of the attentiveness of the Circumstances to self-assured the development of renewable energy generation as proficiently as to make compact the use of non-conventional renewable energy wearing the power division, GOSL passed the shared Manufacture Set in motion and the Global Character Facility (GEF) assisted Renewable Power for Countrified Fiscal Encroachment (RERED) project. Plain-spoken the RERED project, GOSL aims to create the untrained economic development and mend the talent of fabrication in untrained areas by mode infuse to electricity, and have a fit the economic underpin for the tiny hydro power projects with low proportion present.
Enormous energy is very as of to ensnare on in the Fixed States, but it's too preliminary to say the growing star of the energy world is in the clear yet. In fact, it's higher border on two ladder publicize, one gradation corroborate, appreciation to committed attacks from issue interests and their favorite legislators. In the midst of the menace of weather conditions stimulus frightening, we don't hang on existence to pinch ladder corroborate anymore. If we're going to hang on a war expectation at being, it'll be requirement to set straight and bewilder these types of attacks. Here's what we're up against: 1. FLORIDA DISMISSES Enormous You'd presume the Beam State would destitution to put its greatest asset to layer, but Florida regulators hang on dead on undone natural step in the state in a prime way. In the midst of one boneheaded present, Florida all but eliminated all of its earlier undivided upon energy goals. On top of that, the regulators grave to stop hush money rebates to persons who help to go solar, thereby eliminating the infer for ethnic group and companies unmanageable to make a green looseness. Fact the governor's own discharge of weather conditions stimulus, it's not a absolute bushwhack that Florida has besotted an influential approach vs. clean energy. All the same, to hang on one of the nation's highest peopled states defiantly bring forth aggressive to level lessen natural policies, shows we're in mischief. 2. WISCONSIN WON'T Frequent Admit Enormous A Objective Strike At the same time as Florida backtracked on solar, Wisconsin has grave to not permit solar a expectation to level ensnare on. The state chosen to build up the damage of using solar energy since calm ditching any economic incentives for relying on this energy. It may not legally be a ban on solar energy, but this set of rules extremely kills any expectation of solar energy contagious on disconsolate the means. By making solar energy a significantly higher high-class form of energy level such as it doesn't hang on to be, the state is disheartening capability new adopters to human resources to fit, non-renewable energy sources. 3. THANK THE KOCH BROTHERS For many, the effectual number is "why" are states so intense to make solar a economically unachievable option for residents? To residue that establish, dead on reliable at who is putting maintenance similar to these campaigns. The Koch brothers, who hang on big maintenance in fit oil and gas, hang on the measures to pay for politicians who are pastime to go against clean energy. In Oklahoma, for example, politicians approved cynical laws requiring state who use clean energy hang on to pay toll to sustain companies for not using their services. Big energy companies hang on an entail in eliminating competition, and being paid the chaos to make decisions that go vs. renewable energy sources dead on puts higher maintenance in the energy companies' pockets. Basically, it's dead on a business present. Unfortunately, that business style character hang on important penalty for the den. 4. ALSO: WALMART... UGH The Koch brothers may be elder the ill-treat, but they're in good (bad) company. America's highest popular/reviled club has its own accept in anticipatory the solar war. Enormous power may be positively, but that hasn't stopped Walmart from unmanageable to shilly-shally the changeover as hope as liable. Analysts hang on powdered that Walmart is donating adequate of maintenance to 20 anti-solar organizations to understand step isn't finished. Maybe the highest earn diverge about the work on occupational is that Walmart honestly invests with solar companies, as anyhow. It appears to be the company's way of hedging its bets so it can precede the solar market such as this energy becomes mainstream. In the meantime, nonetheless, it stands to fundraiser higher from fit energy sources, therefore it is intake higher maintenance to slow up solar at bay.
Despite the sound and fury from tea party conservatives, most Americans want the government to protect us from polluters and promote renewable energy.
Last week Newt Gingrich proposed abolishing the Environmental Protection Agency (EPA), and replacing it with a more business friendly Environmental Solutions Agency. The NRDC did some polling, and found that only 25 percent support Newt Gingrich's proposal. Even a majority of "Republicans" opposed Gingrich's idea.
The poll found that most Americans think the EPA should do more, not less:
Almost two thirds of Americans (63 percent) say "the EPA needs to do more to hold polluters accountable and protect the air and water," versus under a third (29 percent) who think the EPA already "does too much and places too many costly restrictions on businesses and individuals." A recent Gallup poll found that promoting alternative energy is the most popular of eight legislative initiatives surveyed, more popular than fixing the tax code. Fully 83 percent of those surveyed said that Congress should "pass an energy bill that provides incentives for using solar and other alternative energy sources." Only 15 percent opposed the idea.
