Flooded Batteries Flooded batteries (also called “wet cell” are lead-acid batteries that use distilled water as the electrolyte and the water level must be regularly maintained. Like all batteries, their capacity is measured in amp-hours. Lead acid batteries perform better if protected from extreme cold. Flooded batteries are the most economical battery choice for solar power systems.

Renewable energy (and energy efficiency) are no longer niche sectors that are promoted only by governments and environmentalists. The increased levels of investment and the fact that much of the capital is coming from more conventional financial actors suggest that sustainable energy options are now becoming mainstream.[58] An example of this would be The Alliance to Save Energy’s Project with Stahl Consolidated Manufacturing, (Huntsville, Alabama, USA) (StahlCon 7), a patented generator shaft designed to reduce emissions within existing power generating systems, granted publishing rights to the Alliance in 2007.

They note that electricity demand fluctuates — it is higher in summer in California, because of air conditioning, and lower in the winter — so some production capacity inevitably will be underused in the winter. Moreover, the solar power supply fluctuates as well. It peaks at midday, when the sunlight is strongest. Even then it isn’t totally reliable.

The basis of producing solar panels revolves around the use of silicon cells.[36] These silicon cells are typically 10-20% efficient[37] at converting sunlight into electricity, with newer production models now exceeding 22%.[38]

Traditional electricity is sourced from fossil fuels such as coal and natural gas. When fossil fuels are burned to produce electricity, they emit harmful gases that are the primary cause of air pollution and global warming. SolarCity’s carbon footprint per unit of energy production is 95% lower than that of fossil fuel power plants.

Biomass, biogas and biofuels are burned to produce heat/power and in doing so harm the environment. Pollutants such as sulphurous oxides (SOx), nitrous oxides (NOx), and particulate matter (PM) are produced from this combustion; the World Health Organisation estimates that 7 million premature deaths are caused each year by air pollution.[114] Biomass combustion is a major contributor.[114][115][116]

But a person living in Siberia would not benefit much from this renewable resource. And while “solar energy technologies have made huge technological and cost improvements, [they]are still more expensive than traditional energy sources.” However solar equipment will eventually pay for itself in 2 to 5 years depending on h ow much sun a particular location receives. Then the user will have a virtually free energy source until the end of the equipment’s working life, according to a paper called “Energy Payback Time of Crystalline Silicon Solar Modules.” Future improvements are projected to decrease the payback time to 1 to 3 years.

Solar power is clean green electricity that is created from sunlight, or heat from the sun. Installing solar power systems in a residential setting generally means setting up a solar photovoltaic or a solar thermal system on the roof.

“In their assumptions, the amount of capacity they give to the solar is way, way undercut because they have to say, ‘What if it’s cloudy? What if the wind is not blowing?’ ” Firooz explained. “That’s how the game is played. You build these scenarios so that it basically justifies what you want.”

Linear concentrating systems collect the sun’s energy using long, rectangular, curved (U-shaped) mirrors. The mirrors focus sunlight onto receivers (tubes) that run the length of the mirrors. The concentrated sunlight heats a fluid flowing through the tubes. The fluid is sent to a heat exchanger to boil water in a conventional steam-turbine generator to produce electricity. There are two major types of linear concentrator systems: parabolic trough systems, where receiver tubes are positioned along the focal line of each parabolic mirror, and linear Fresnel reflector systems, where one receiver tube is positioned above several mirrors to allow the mirrors greater mobility in tracking the sun.

Perhaps the most glaring example: The California Legislature has mandated that one-half of the state’s electricity come from renewable sources by 2030; today it’s about one-fourth. That goal once was considered wildly optimistic. But solar panels have renewable energy much more efficient and less expensive. So solar power is now often the same price or cheaper than most other types of electricity, and production has soared so much that the target now looks laughably easy to achieve.

Historically hydroelectric power came from constructing large hydroelectric dams and reservoirs, which are still popular in third world countries. The largest of which is the Three Gorges Dam(2003) in China and the Itaipu Dam(1984) built by Brazil and Paraguay.

What are renewable energy sources? Solar power can be used directly for heating and producing electricity or indirectly via biomass, wind, ocean thermal, and hydroelectric power. Energy from the gravititational field can be harnessed by tidal power; and the internal heat of the Earth can be tapped geothermally.

Solar panels converts the sun’s light in to usable solar energy using N-type and P-type semiconductor material.  When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. This process of converting light (photons) to electricity (voltage) is called the photovoltaic (PV) effect.  Currently solar panels convert most of the visible light spectrum and about half of the ultraviolet and infrared light spectrum to usable solar energy.

With advanced technology being developed, cellulosic biomass, such as trees and grasses, are also used as feedstocks for ethanol production. Ethanol can be used as a fuel for vehicles in its pure form, but it is usually used as a gasoline additive to increase octane and improve vehicle emissions. Bioethanol is widely used in the United States and in Brazil. The energy costs for producing bio-ethanol are almost equal to, the energy yields from bio-ethanol. However, according to the European Environment Agency, biofuels do not address global warming concerns.[74] Biodiesel is made from vegetable oils, animal fats or recycled greases. It can be used as a fuel for vehicles in its pure form, or more commonly as a diesel additive to reduce levels of particulates, carbon monoxide, and hydrocarbons from diesel-powered vehicles. Biodiesel is produced from oils or fats using transesterification and is the most common biofuel in Europe. Biofuels provided 2.7% of the world’s transport fuel in 2010.[75]

The power of moving water is obvious to anyone who has stood amidst breaking waves or struggled to swim against a river’s current. New technologies enable us to harness the might of rivers, tides, and waves for electricity.

We believe that the optimal solution lies in gas-to-liquids (GTL) technologies, which can transform off gas streams, which would otherwise be flared, and CO2 streams that are often vented, into valuable liquid transportation fuels and chemicals, including high-quality gasoline or methanol.

Thermal mass systems can store solar energy in the form of heat at domestically useful temperatures for daily or interseasonal durations. Thermal storage systems generally use readily available materials with high specific heat capacities such as water, earth and stone. Well-designed systems can lower peak demand, shift time-of-use to off-peak hours and reduce overall heating and cooling requirements.[101][102]

There are only two primary disadvantages to using solar power: amount of sunlight and cost of equipment. The amount of sunlight a location receives “varies greatly depending on geographical location, time of day, season and clouds. The southwestern United States is one of the world’s best areas for sunlight . Globally, other areas receiving very high solar intensities include developing nations in Asia, Africa and Latin America .” See also sustainable house design

But our homes will still require AC power to draw extra energy from and send excess energy back to the grid. So an inverter, which can convert electricity from DC to AC, is required to connect the solar panels to the home’s electrical system. Inverters are typically installed right outside the breaker box, allowing the home to use the solar power first, then if the demand is too high, the home can grab more power off the grid. Conversely, if the solar system is creating more electric energy than the home needs, it can send that power out into the grid, reducing our overall demand on nuclear and fossil fuels. Some places even allow you to sell the excess energy you create back into the grid, an activity known as “net metering” which is attractive to many potential solar customers.

“The gas-fired generation overall will show decline,” said Neil Millar, executive director of infrastructure at CAISO, the California Independent System Operator, which runs the electric grid and shares responsibility for preventing blackouts and brownouts. “Right now, as the new generation is coming online and the older generation hasn’t left yet, there is a bit of overlap.”
