When it comes to trying to define "to be energy efficient" or "energy efficiency", there does not seem to be a single commonly-accepted definition of energy efficiency due to differing perspectives. Refridgerators and Freezers: refrigerator models use at least 20% less energy than required by current federal standards and 40% less energy than the conventional models sold in 2001. Compact Flourescent Light Bulbs: use about 75% less energy than standard incandescent bulbs and last up to 10 times longer. Computer Monitors: use from 25-60% less electricity than standard models, depending on how they are used. Combined heat and power (CHP)or cogeneration: an efficient, clean, and reliable approach to generating power and thermal energy from a single fuel source. Less power is needed by end user which lessens the amount of pollution created by power plants.
The Department of Energy is committed to reducing America's dependence on foreign oil and developing energy efficient technologies for buildings, homes, transportation, power systems and industry.
The Energy Efficiency and Renewable Energy (EERE) Program develops sustainable energy technologies to create a cleaner environment, a stronger economy, and a more secure future for our nation. The New Hampshire Residential Energy Performance Association (REPA) is an organization made up of individual Residential Energy Auditors and Weatherization Professionals providing energy efficiency services in NH.
Cities for Climate Change Protection: ICLEI provides technical consulting, training, and information services to support local governments in the implementation of sustainable development initiatives. Ours is a steam power plant that uses refrigerant instead of steam (it's called an ORC Rankine cycle). Well, it used to be a Rankine cycle until we eliminated the working fluid feed pump, and replaced it with our own patented method for recycling the working fluid. The important thing is that the heat source only needs to be about 40oF hotter than the surrounding environmental temperature (ambient). It's economical for cogeneration, being fueled by man-made renewable thermal sources including waste heat from factories, freezers, refrigerators, air conditioners, and the heat by-product from fuel cells. It's also mighty handy for remote applications fueled by cheap solar collectors, normally-ignored-'warm'-geothermal sources, bio fuels, chimneys, firewood, trash, or any other source of warmth. In an effort to reduce the 'actual' inefficiency of very low temperature Rankine cycles, our patented power plant eliminates the working fluid feed pump.
Most 'alternative' thermal energy is found at a temperature below that of steam or boiling water (below 212o F). Compared to 'alternative' thermal sources, commercial 'organic Rankine cycle' power plants generally require heat sources hotter than those that are economically obtained from renewable sources. The cost of naturally occurring renewable energy is a result of the cost of the collection apparatus multiplied by the efficiency of the power plant. The upshot of the patented Matteran cycle is that it is predicted to make economical power at Rankine cycle efficiencies within any temperature range, whereas 'organic Rankine cycles' become less economical at the lower energy end of the environmental thermal spectrum.
Sunshine is free, but consider the cost of a large, curved, shiny mirrored assembly that must swivel to track the sun, and concentrate sunshine into a 400o-700oF fluid. Compare that to the cost of a simple immobile flat plate collector, producing equal Btu's per square meter, but at a temperature of 150oF.
One might propose that the higher temperatures produced by the parabolic collector would produce a Rankine cycle of a higher efficiency. Two hundred feet beneath the surface of most of the State of Nevada, (and much of the West, there exists a geothermal temperature averaging 160o Fahrenheit. A similar logic applies to co-generated energy, which is more abundant at temperatures below 250o Fahrenheit than above it. And, needless to say, steam boilers are out of the question for remote residential applications. It's quite possible that the sole opportunity to operate an economic OTEC power plant based on its electric output might be limited to our own thermodynamic cycle. Renewable heat sources are rarely suited to the temperature requirements of modern thermal power plants. In comparison to conventional hydrocarbon fuels such as coal or oil in generating electricity, the cost of solar energy is significantly higher. In our example, a ton of coal on the average produces approximately 6,182 KWH of electric at a cost of about $36 per short ton (2,000 pounds).
In comparison to solar energy, the hydrocarbon fuel costs are significantly lower without rebates, tax benefits nor the cost of carbon emissions.
Some of the considerations for a solar energy system include the 20-to-30 year lifespan of the system and the hours of available sunlight. In order to compare the solar energy costs to conventional hydrocarbon fuels, we must covert the $8.95 per into KWH. So a $45,000 5KW solar energy system produces about 119,246 KWH of electric over its lifespan meaning the average cost equals $0.38 per KWH. The relatively high solar energy costs in comparison to conventional fuels should improve with utility rebates and government tax incentives. We will explore the some of the advances in thin-film technologies, the declining costs of solar panels, and the improving solar conversion efficiencies that should continue to bring solar energy costs on par with hydrocarbon fuels.
I would like kindly ask the cost of solar energy for desalination and and energy generation and the area to be allocated per 0ne MWH solar energy generation. I have a 3k system on my roof and it produces annually between 4,700 and 4,900 kwh of electricity, so your calculations are clearly understating the kwh generation of better systems on well-oriented roofs (my panels are Suntech). But let’s assume I get 25 years at original efficiency and only another 10 years at 90% efficiency. Note that by putting a solar system on my roof I have LOCKED IN the price per kwh of 4.4 cents per watt for the next 40 years. As for the stated price of coal per khw in this article, this is meaningless to a homeowner.
Oh, and this return is entirely TAX FREE because it represents a savings of a necessary expense and not interest or dividend income from Mr. Sanyo's Solar Ark, located in the Gifu Prefecture at the center of Japan, is a 315m-wide (1033 feet), 37m-tall (121 feet) solar photovoltaic power generation facility. Conventional sources of generating electricity, including coal and oil, have historically been much cheaper than renewables. The direct current (DC) solar power is converted to alternating current (AC) so that it can be used in residences and businesses.
Total electric output is the product of the average peak hours of sunlight (4.0 hours per day), the number of days in the year, and the lifetime of the system.

Many companies, for example, Sharp Solar, provide cost calculators on their websites to help building owners make these calculations by providing geographical location information with respect to sunlight, rebates and tax incentives.
David enjoys research and writing about cutting edge technologies that hold the promise of improving conditions for all life on planet earth. If you're new here, and just looking for information about local solar installers, you can Click Here to request a free cost estimate for your home.
State Renewable Energy Credits – Many states, like New Jersey and Massachusetts, have developed credit markets.
Net-metering – In some areas your utility will pay you for an extra electricity you send back to the grid. Local Incentives – Local utilities and municipalities (LA is a great example) have their own solar energy subsidies.
This is also extremely important: are you looking to offset part of your bill or all of it?
The amount of energy you need directly translates into hardware, in this case the number of solar panels your system will require. Another thing this highlights is the importance of energy efficiency first: if you can cut your power bill before you go solar, everything will cost less. If you decide to lease a system (generally called a PPA or Power Purchase Agreement), you get the benefits of electricity savings without the big up-front cost.
Get Your Dose of Solar FactsWe are just entering the era of Solar Energy, but with less than 1% adoption in the United States, we have a long way to go. Solar Energy Facts is here to help you dispel myths, learn more about home solar, and decide if solar panels are right for your home. Last month First Solar (FSLR) achieved a milestone in the solar industry with its announcement of $1 per Watt reducing its production cost for solar modules to 98 cents per watt, thereby braking the $1 per watt price barrier.. In addition, Barron’s published an article (March 30, 2009)_ Nightfall Comes to Solar Land providing unique insight into the economics of solar PV suppliers.
However, the PV panels typically represent approximately half the cost of a solar energy system.
As illustrated in Figure 1, the panels represent a significant cost of installation, but the labor and support brackets for the PV panels are significant as well. In Figure 2 Green Econometrics is comparing PV efficiency as measured by watts per square meter versus cost per watt.
A comparison of wind and solar energy costs is demonstrated by Detronics and offers a useful framework to compare wind and solar costs by kilowatt-hour (KWH). The Alternative Energy Pricing chart was base on research from Solarbuzz which is one of the leading research firms in solar energy.
The bottom line is that despite the lower PV panel costs; we are still not at parity with hydrocarbon fuels such as coal and oil.
Use the controls in the far right panel to increase or decrease the number of terms automatically displayed (or to completely turn that feature off).
When you account for the effects which are not reflected in the market price of fossil fuels, like air pollution and health impacts, the true cost of coal and other fossil fuels is higher than the cost of most renewable energy technologies. A 2013 report published by the International Monetary Fund concluded that global fossil fuel subisides amount to $1.9 trillion annually. Another study by economists Muller, Mendelsohn, and Norhaus (MMN11) looked at just the external costs associated with the damage done by air pollution, and arrived at a best estimate of 3.6 cents per kWh of external costs, despite being unrealistically conservative (Figure 2). Comprehensive comparative analyses of life cycle costs of all electricity generation technologies and practices are needed to guide the development of future energy policies. Begin phasing out coal and phasing in cleanly powered smart grids, using place-appropriate alternative energy sources.
A healthy energy future can include electric vehicles, plugged into cleanly powered smart grids; and healthy cities initiatives, including green buildings, roof-top gardens, public transport, and smart growth. Alternative industrial and farming policies are needed for coal-field regions, to support the manufacture and installation of solar, wind, small-scale hydro, and smart grid technologies. We must end mountaintop removal (MTR) mining, reclaim all MTR sites and abandoned mine lands, and ensure that local water sources are safe for consumption.
To transform our energy infrastructure, we must realign federal and state rules, regulations, and rewards to stimulate manufacturing of and markets for clean and efficient energy systems. In the USA, there is no correlation between state renewable electricity production and electricity price (Figure 3) or renewable production and electricity price increase over the past two decades (Figure 4). Figure 3: State renewable (excluding hydroelectricity) electricity percentage of total electricity generation vs.
If deploying renewable energy does not raise electricity prices, then clearly it is not an expensive proposition. We may not pay the costs of climate change, lost biodiversity, air and water pollution, adverse health effects, etc. Also of interest, this IPCC SRREN 2011 figure : range in recent levelized cost of energy for selected commercially available RE technologies in comparison to recent non-renewable energy costs. It must be precised that this is the cost for producing electricity (or heat, or fuel) from RE local units, but a global energy transition will require additional costs : to transform the infrastructure of distribution (grid) and to electrify many final uses (for example public transport).
As your article put it, the true cost of fossil sources is underestimated because externalities (climatic and non-climatic) are ignored by market. The question of how to implement policies that make perfect sense but don't match the party line is a political one, unique to each nation. Bjorn Lomborg has a column today in USA Today where he is promoting more fracking as the best approach to global warming.
Since I am not a climate scientist, but rather a patent attorney with a mechanical engineering background that is growing staler by the year, I hesitate to call BS on Lomborg's claim, but it smells very fishy to me, so I would be interested to hear what people here have to say.
The average efficiency of fossil-fueled power plants in the United States is 33%; CHP systems typically achieve total system efficiencies of 60 to 80% for producing electricity and thermal energy. Green Building Council (USGBC) is a non-profit organization committed to expanding sustainable building practices.
The Program is committed to expanding energy resource options and to improving efficiency in every element of energy production and use.
Our objective is to improve and expand our understanding, skills, and delivery of the "House as a System" residential energy efficiency technology.
Power plants based on this technology will produce electricity, hydrogen, air conditioning, refrigeration, hydraulic power, and irrigation.
We replace it with a simple method for cycling the spent working fluid, effectively freeing the cycle of a principle component of its mechanical inefficiency.

Modern geothermal power plants require a minimum heat source of 320o F, largely in consequence to the mechanical inefficiency of the mechanical feedpump required by all Rankine cycles. One drilling company in Reno has drilled more than 3,000 geothermal wells for heating homes, swimming pools, and spas. Our power cycle operates at temperatures and pressures typical of air conditioning and refrigeration apparatus. Thus, our unique opportunity is to help bring to the market power plants optimized for these unused and overlooked thermal resources.
Although you don’t really go on to say how good of an investment solar energy actually is, in the long run. You are not considering the cost of pollution and environmental degradation related to fossil fuels (coal, oil and gas) energy. Its design was inspired "by the vision of an ark embarking on a journey towards the 21st century", a symbol of Sanyo's goal of achieving a "clean energy society." At the center of the Solar Ark is an unusual museum of solar energy, called Solar Lab, which helps to raise children's awareness to global environmental issues, making science more interesting and appealing. A ton of coal produces about 6,000 KWH of electricity for about $40 per short ton (2,000 lbs.) A barrel of oil produces 1,700 KWH at a cost of about five cents per KWH when the price of oil is about $75 per barrel. It is common to consider the lifetime of the installation and the number of hours of available sunlight, which changes with location.
While some incentives are nation-wide, like the Federal solar tax rebate, most of the cost of your system has to do with where you live. Sometimes just knocking off a part of the bill can give you huge monthly electricity cost savings, as in the case of tiered electricity rates. The primary variables that determine the cost-benefit here are your electricity usage now (big or small bill?) as well as local electricity rates (average or expensive). If you buy the system you’ll see big up-front costs, but you also reap all the benefits of tax credits, renewable energy credits, and other financial incentives. The only catch is that another company owns the system, so you might not get to claim all the credits and rebates available.
Don’t worry, your local solar installer will be able to explain the options available in your area. Working Group I Contribution to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, Annex I, Glossary, pp.
Such a transformation would be beneficial for our health, for the environment, for sustained economic health, and would contribute to stabilizing the global climate. Ones hopes that the politics will become more favorable as the climate becomes more unstable. One of the things that struck me was that he seemed to keep comparing the full cost of reducing global warming with the spot price of fixing one symptom by other means.
Their mission is: to transform the way buildings and communities are designed, built and operated, enabling an environmentally and socially responsible, healthy, and prosperous environment that improves the quality of life. However, the greater expense for the collectors far outweighs the benefits of a power cycle that would convert, for example, that 40X more-expensive thermal energy into 4X more power.
However, even with an unlimited demand for residential and small commercial power plants, 'organic Rankine cycles' do not produce economical electricity from these low-grade geothermal resources.
Renewable thermal energy sources are non-polluting They are either a byproduct of our industrial processes or easily collected from the biosphere. If the average peak sunlight hours per day is 4.0, the average annual output of the solar energy panels can be calculated. In addition to the total electric output, utilities offer rebates and governments offer tax incentives that should be calculated and taken into account when assessing a project’s overall costs. In New Jersey, for example, conventional electricity currently costs about $.17 per kilowatt hour (KWH). Once the system pays itself off (by saving you money on electricity as well as other rebates), which generally takes about 5-10 years, it’s like having free electricity. With increased efficiency and improved materials,solar energy will be cheaper in the coming years especially CSP. Many economists agree on that point and it is unfortunate that policymakers delay their decision. He never added up all the individual spot prices to get a total cost of dealing with global warming.It struck me as being somewhat akin to trying to decide whether or not to replace the roof shingles.
To make electricity it takes heat from something warm, processes the heat into power, and then dumps the majority of that heat back to the earth. It appears that Matteran's cycle may be satisfactorily economic in just such an application. So multiply the cost per KWH number for solar some 2-3 times to get more realistic picture.
All the more so that the actual dependency to fossil ressources threatens economy in case of high volatility. A roofing job would cost $X, but patching the ceiling costs a lot less - so just patch the ceiling. Solar at this time is completely lacking any commercial viability for most people and businesses.
A roofing job would cost $X, but replacing bulbs in the shorted electrical system costs a lot less - so just replace light bulbs. So he describes the benefits of current solar PV in Germany alone vs the benefits of future fracking on a global level. A roofing job would cost $X, but replacing the carpet costs a lot less - so just replace the carpet. A roofing job would cost $X, but painting the walls costs a lot less - so just paint the walls. Eventually, all the different repairs end up adding up to a lot more than replacing the roof, so the sensible home owner would replace the roof. But if you're working for the trade association that represents drywall, electrical, paint, and carpet trades - and excludes the roofing indistry - then it's to your advantage to try to mislead the home owner so they don't get the roof fixed.
That is, he is assuming emission reduction strategies will not work to argue that they are ineffective.
