Promoting Clean, Renewable Energy: Investments in Wind and Solar Home | Executive Summary | Introduction | Transportation | Renewable Energy | Private Sector | Medical Research Three decades ago, the U.S. led the world in the development of renewable energy, such as wind, solar, and geothermal power. Since then, markets for renewable energy have grown predominantly overseas due to strong, consistent foreign government incentives and policies. As a result, manufacturing of renewable energy equipment has grown largely overseas as well. Recovery Act investments are helping the U.S. re-establish leadership in innovation, manufacturing, and deployment in these fast-growing industries, which will create new jobs, increase access to clean energy, and reduce greenhouse gas emissions. In the beginning of his Administration, President Obama set a goal of doubling U.S. renewable energy generation capacity from wind, solar, and geothermal by 2012.

Annual cost of environmental damage is $6.6 trillion, says UN The grim numbers come from a study (PDF) released Wednesday by the UN-backed Principles for Responsible Investment (PRI) and UNEP Finance Initiative. The most environmentally damaging business sectors have been identified as utilities; oil and gas producers; and industrial metals and mining. The three together accounted for almost a trillion dollars’ worth of environmental harm in 2008. The top 3,000 companies by market capitalisation, which represent a large proportion of global equity markets, were responsible for $ 2.15 trillion worth of environmental damage in 2008. The report, titled Universal Ownership: Why environmental externalities matter to institutional investors, projects that the monetary value of annual environmental damage from water and air pollution, greenhouse gas emissions, general waste and depleted resources could reach $28.6 trillion in 2050, or 23 percent lower if clean and resource-efficient technologies are introduced.

The solar age is upon us It is the sheer volume of PV being installed that is crashing the price of solar. We need this hell-for-leather growth to continue for a few more years, supported where necessary by tax and regulatory support. The International Energy Agency published a report yesterday that focuses on the rapid decline in the cost of renewable energy. More precisely, Projected Costs of Generating Electricity: 2015 Edition says that electricity costs from wind and solar have plunged, a word rarely used by international civil servants. On good sites around the world, renewables are now cheaper than fossil fuels. Bizarrely, the IEA says that new nuclear is also inexpensive, a conclusion strikingly at variance with the rampant inflation in construction costs around the world. It may be that the absurd optimism over nuclear is influenced by the joint author of this report, the Nuclear Energy Agency. This note looks at how today's figures compare with the previous 2010 edition of this report. What about wind?
August: Joint IEA-NEA report details plunge in costs of producing electricity from renewables Analysis shows nuclear energy competitive with other baseload power sources 31 August 2015 The cost of producing electricity from renewable sources like wind and solar has been falling for several years. The report, Projected Costs of Generating Electricity: 2015 Edition, also shows that new nuclear power plants generate electricity more cheaply than other established “baseload” sources such as coal- and gas-fired power plants over the full lifetime of facilities when financing costs are relatively low. The report, a joint project by the International Energy Agency and the Nuclear Energy Agency, calculates the cost of producing electricity from different types of new power plants. No single technology proves the cheapest form of electricity generation under all circumstances: many factors determine the final cost of any investment, principally local influences such as market structure, policy environment and resource endowments.

Why Use Solar Electricity? When we consider the true cost of energy, we need to look at the big picture, not just the rate on the utility bill. Conventional fuels have real social, environmental, and economic impacts. There are annual and cumulative costs that stem from all of the pollutants (airborne, solid, and liquid) emitted from mining, processing, and transporting fossil fuels that impact our public health and the environment. Electricity derived from coal and natural gas will never be able to outweigh the energy and continual resources required to produce it. Grid electricity is paid for as you use it, with payments stretching out forever. Independence is chief among the reasons for wanting an off-grid PV system where the grid is available. When weighing the energy options (between the grid and solar, wind or water sources) it becomes apparent that solar energy is a very democratic form of energy.
Solar 101 | Yingli Solar From Sand to Sun Step 1: Sand Learn how a humble bit of dirt attains the power to turn sunlight into electricity. sand silicon ingot Most solar panels produced today are made from Silicon, the second most abundant element on Earth and the primary ingredient in beach sand. To do this, we put hundreds of pounds of silicon chunks (i.e. rocks) into a giant crucible and add a little boron (called a ‘dopant’) to give the silicon positive polarity. We let the large silicon ingot cool down before slicing it into thin wafers using wire saws. The next step is to reduce the reflectivity of the wafer from about 30% to 10% through a chemical surface texturing process that creates tiny pyramids on the wafer’s surface. It's time to turn our silicon wafer into something that converts sunlight into electricity. Now we have a photovoltaic (photo = light, voltaic = energy; thus, “light into energy”) device!

Solar Reviews | Consumer Reviews of Solar Companies and Solar Panels Growth in residential electricity prices highest in 6 years, but expected to slow in 2015 March 16, 2015 Source: U.S. Energy Information Administration, Electric Power Monthly and Short-Term Energy Outlook Residential electricity customers in most areas of the country experienced large increases in retail electricity prices during 2014, with the average U.S. residential price increasing 3.1% over the previous year. The increase represents the highest annual growth rate since 2008. Residential electricity rate increases during 2014 ranged from 1.3% in the Pacific Coast states to 9.9% in New England. Despite recent increases, retail electricity prices have historically risen at a lower rate than the general rate of inflation, and the real price of electricity is lower than it was prior to 1995. Source: U.S. The electricity industry likely will continue to invest in upgrades to transmission and distribution systems in the coming years as well as expand renewable generating capacity, the costs of which will be passed through to retail customers.
