Solar Panel Efficiency
Solar panels are made up of solar cells. The electricity produced from one solar cell is minimal, so a number are linked to form solar panels – which should create a significant amount of power. Silicon cells make up the most typically used solar panels (also called Photo Voltaic or PV modules) which produce a as much as 50 Watts of electricity in bright sunlight. To generate even more energy, solar panels can be interconnected.
By connecting to the grid, people who create solar energy can be paid by the utilities for any extra electricity they produce. Net metering (which is allowed in 30 states) tracks a solar power system’s electricity production and allows producers to sell excess electricity back to the utilities. The most frequently used option is a single, reversible meter. As electricity is produced by the solar power system, on-site demand is fulfilled first. Then, rather than being battery-stored, the extra electricity is sent back into the grid, and turns the electric meter backwards. The utility company then credits the homeowner at the end of each metering period.
CertainTeed to Offer Solar-Integrated Roofing Products
CertainTeed, one of the nation’s largest roofing manufacturers, has partnered with a solar technology developer to produce solar-integrated roofing products by 2010.
CertainTeed, based in Valley Forge, Pa., is a major player in the residential roofing market so the widespread availability of solar-integrated roofing could become critically important to green building efforts and the renewable energy market. The plan is also significant for what it could mean for the perception that solar panels are an eyesore.
“It was critical for us to provide photovoltaics not just for energy, but for the aesthetics as well,” says Husnu Kalkanoglu, CertainTeed’s vice president of research and development for the company. Because the solar will be blended into the roof the panels will be less obtrusive from the curb, which could further spur interest from home buyers and builders. (Many homeowners’ associations have rules against roof-mounted solar collectors in their developments.)

Solar Energy Facts – Getting A Quick Look At What The Sun’s Rays Has To Offer
Solar energy facts are speedilydiscoveredon the internet. Solar technology is easily the mostoffered energy resource well-known to man these days. Definitely, there isjust no fossil fuel on this environment which givesmost of us with the infinite energy possibilities which Solar power can. Of all the solar facts that 1 can discover, some of the most essential solar energy facts revolve around the advantages that solar has to supply.
The sun is usually there shining and even on cloudy days there’s still energy that’s being emitted from the sun. For solar facts you also want to know that sunlight is a clean and renewable source of energy and so you never have tobe worried about it running out. I hope these solar energy facts werehelpful to you. You are able to also go via solar energy’s positives and negatives for additionalinformation and facts on this subject. Lastly, it could bereally said that solar power can be a boon to human beings.
Ocean Current Energy
Ocean Current Energy
The relatively constant flow of the ocean currents carries large amounts of energy that can be captured and converted to a usable form.
Ocean waters are constantly on the move. Ocean currents flow in complex patterns affected by the wind, water salinity and temperature, topography of the ocean floor, and the earth’s rotation. The ocean currents are driven by wind and solar heating of the waters near the equator, though some ocean currents result from density and salinity variations of water. These currents are relatively constant and flow in one direction only, in contrast to the tidal currents closer to shore. Some examples of ocean currents are the Gulf Stream, Florida Straits Current, and California Current.

U.S. government drafts fast track solar energy policy
“It’s time to harness these resources and lead in the global clean energy economy. Today’s announcement is part of an integrated strategy to cultivate the entire innovation chain to create the jobs of the 21st century economy and to put America on a sustainable energy path,” Energy Secretary Steven Chu said in a statement.
The United States Department of the Interior announced Thursday that it has drafted new environmental policy to fast track utility scale solar power projects in six western states.
