When water is used to generate electricity, it is called hydroelectric power, or hydropower. Most hydropower plants use a dam on a river to create a reservoir to store water. As water is released from the reservoir, it flows through a turbine and causes it to spin. This activates a generator that produces electricity.

Solar water heaters reduce the need for conventional water heating by about two-thirds and pay for their installation within 4 to 8 years with electricity or natural gas savings. Compared to those with electric water heaters, Florida homeowners with solar water heaters save 50 to 85 percent on their water heating bills, according to the Florida Solar Energy Center.[59]

In 2010, the International Energy Agency predicted that global solar PV capacity could reach 3,000 GW or 11% of projected global electricity generation by 2050—enough to generate 4,500 TWh of electricity.[38] Four years later, in 2014, the agency projected that, under its “high renewables” scenario, solar power could supply 27% of global electricity generation by 2050 (16% from PV and 11% from CSP).[2] In 2015, analysts predicted that one million homes in the U.S. will have solar power by the end of 2016.[39]

WASHINGTON – America’s transition to a clean energy economy is irrevocably underway and delivering deep pollution reductions, with coal use at record lows but renewable energy higher than ever, according to the Fourth Annual Energy Report released today by the Natural Resources Defense Council (NRDC). One sign of how far things have advanced: more than one-fifth of the U.S. population lives in a state with a goal of at least 50 percent renewable energy.

Scientists from Spectrolab, a subsidiary of Boeing, have reported development of multi-junction solar cells with an efficiency of more than 40%, a new world record for solar photovoltaic cells.[6] The Spectrolab scientists also predict that concentrator solar cells could achieve efficiencies of more than 45% or even 50% in the future, with theoretical efficiencies being about 58% in cells with more than three junctions.

One of the most significant obstacles to making most renewable energy sources competitive with more widely adopted energy sources is that they are relatively dilute. In fact, some of today’s more promising processes for tapping biomass energy involve using chemical or thermal conversion in an attempt to mimic the results of a process that, through immense pressure and over geologic time scales, created energy-rich fossil fuels from biomass. Despite such developing technologies, the amount of energy in a given amount of raw biomass tends to be significantly less than that contained in an equal amount of its concentrated cousin, fossil energy. In the United States, demand for all sources of energy is expected to rise between now and 2040 to keep pace with growth in the economy, population and standard of living. Renewable sources are anticipated to participate more broadly in this growth being spurred by State and Federal legislation, including the Energy Independence and Security Act of 2007.

In 2016, about 10% of total U.S. energy consumption was from renewable energy sources (or about 10.2 quadrillion British thermal units (Btu)—1 quadrillion is the number 1 followed by 15 zeros). About 55% of U.S. renewable energy use is by the electric power sector for producing electricity, and about 15% of U.S. electricity generation was from renewable energy sources in 2016.

Solar thermal power systems may also have a thermal energy storage system component that allows the solar collector system to heat an energy storage system during the day, and the heat from the storage system is used to produce electricity in the evening or during cloudy weather. Solar thermal power plants may also be hybrid systems that use other fuels (usually natural gas) to supplement energy from the sun during periods of low solar radiation.

Leaders in China and India are also turning to wind and solar power to reduce climate change pollution and sustain economic growth. In China, NRDC supports the development of a flexible power grid capable of handling a high penetration of renewable energy, and we promote policies that help utilities manage that new influx. In India, we advise government officials on meeting the nation’s solar energy and wind goals and adopting financial structures that encourage clean energy projects. And in Latin America, NRDC works with local partners to encourage governments to focus on developing their renewable sectors instead of continuing to rely on fossil fuels.

Demand Response: People, not New Power Plants, are Driving the Clean Energy Future. To take full advantage of low-carbon, renewable energy sources, we need a power grid with enough flexibility to harness clean energy when it is available and abundant.

Green Energy is energy that can be extracted, generated, and/or consumed without any significant negative impact to the environment. The planet has a natural capability to recover which means pollution that does not go beyond that capability can still be termed green.

For merchant solar power stations, where the electricity is being sold into the electricity transmission network, the cost of solar energy will need to match the wholesale electricity price. This point is sometimes called ‘wholesale grid parity’ or ‘busbar parity’.[5]

Geothermal energy comes from heat produced naturally inside the Earth. Geothermal reservoirs are underground areas of steam or hot water that can be used to produce electricity or heat for our needs. Geothermal pumps can be used to move heat from the Earth into homes during the winter and move heat from homes back to the Earth during the summer. This works because the temperature just beneath the Earth’s surface remains fairly constant throughout the year, and it is hotter than the air in winter but cooler than the air in summer.

Solar photovoltaic (PV) devices, or solar cells, change sunlight directly into electricity. Small PV cells can power calculators, watches, and other small electronic devices. Arrangements of many solar cells in PV panels and arrangements of multiple PV panels in PV arrays can produce electricity for an entire house. Some PV power plants have large arrays that cover many acres to produce electricity for thousands of homes.

It’s hard to decide what I am most impressed with concerning NW Wind and Solar’s installation… the clear outline of what they would do, all the background work they did with certifications and permissions, the updates they gave me along the way, the fast responses to my questions, the yearly production incentives and federal tax credits, or the fact that nearly all of the electricity my family will use in a year will be met by solar power!

Technology improvements and policies to promote research, development, and installation of solar have resulted in tremendous drops in the cost of solar power over the past several years. Even without taking important health and safety costs (note that a Harvard study concluded in 2011 that the health costs of coal are $500 billion a year in the U.S.), environmental costs, energy security costs, and other social costs into account, solar is already cost-competitive with new electricity from conventional energy options like coal and https://www.youtube.com/edit?o=U&video_id=ZSB8VSoGFjg energy (if you take into account how long it would take coal or nuclear plants to get built) — see the graphs below.

Solar energy is most sought today in developing countries, the fastest growing segment of the photovoltaics market. People go without electricity as the sun beats down on the land, making solar power the obvious energy choice. “Governments are finding its modular, decentralized character ideal for filling the electric needs of the thousands of remote villages in their countries.” It is much more practical than the extension of expensive power lines into remote areas, where people do not have the money to pay for conventional electricity.

Producing liquid fuels from oil-rich varieties of algae is an ongoing research topic. Various microalgae grown in open or closed systems are being tried including some system that can be set up in brownfield and desert lands.

Renewable energy projects in many developing countries have demonstrated that renewable energy can directly contribute to poverty reduction by providing the energy needed for creating businesses and employment. Renewable energy technologies can also make indirect contributions to alleviating poverty by providing energy for cooking, space heating, and lighting. Renewable energy can also contribute to education, by providing electricity to schools.[138]

And, despite critics’ complaints that moving to renewables would stymie economic growth and increase the electric bills of customers throughout the state, it’s actually been quite the opposite. In the last seven years, California has seen a massive construction boom in the solar- and wind-energy sectors. The price of solar power has dropped to under $30 in 2016 from around $136 per megawatt-hour in 2008, while wind power prices have fallen to $51 in 2015 from $97 per megawatt-hour in 2007, per the report. Over the same period, the state has seen greenhouse-gas emissions from electricity generation decrease nearly every year.

    The California Solar Initiative offers cash incentives on solar PV systems of up to $2.50 a watt. These incentives, combined with federal tax incentives, can cover up to 50% of the total cost of a solar panel system.[102] Financial incentives to support renewable energy are available in some other US states.[103]

    Solar energy utilization requires solar (i) capture and conversion and (ii) storage. Solar capture and conversion may be accomplished by photovoltaics (PVs). The challenge here is to dramatically reduce the cost per W of delivered solar electricity. Compared with fossil energy, solar energy is diffuse, and hence materials costs must be very inexpensive to make a solar-based process economical. Knowing the insolation striking an area of the earth for a 30-yr period, it is relatively simple to calculate the sale price of the converted energy that is needed to pay back at least the initial cost that is required to cover that area with the solar energy conversion system. At 10% efficiency, and a cost of $300 m−2, both typical of current Si-based solar electricity modules, along with a balance of systems cost of $3 Wp −1 (peak W), an electricity price of $0.35 [kW-hr]−1 is required to cover the initial system costs (13). By comparison, fossil-derived electricity (high-value energy) now costs approximately $0.02–0.05 [kW-hr]−1, and that cost includes storage and distribution costs. To reach a cost point near that of fossil-derived energy will thus require improvements in efficiency but additionally will require large decreases in cost, into a range below $100 m−2. For comparison, the cost of paint is about $1 m−2, so the solar energy conversion system can cost ≈10 times more than the cost of paint, but not much more if it is to provide cost-effective primary energy.
    A parabolic trough collector has a long parabolic-shaped reflector that focuses the sun’s rays on a receiver pipe located at the focus of the parabola. The collector tilts with the sun to keep sunlight focused on the receiver as the sun moves from east to west during the day.
