The sun - a Reliable Source of Energy

The United States is well suited for the use of solar power. Most of the nation is exposed to high levels of irradiation every day. Even in parts of the nation confronted with rainy summers and dark winter months, solar power can still be put to use economically.

Depending on the location, the average annual amount of energy PV modules will be exposed to totals between 950 to 2,150 kilowatt hours per square meter (kWh/m2). This is a lot considering that 1,000 kWh/m2 is equal to the energy of about 25 gallons of heating oil. So you can see that the energy potential is already there and PV systems are an excellent way to put it to work for you.

Cap-and-trade program would raise electricity prices, utility study says
Apr. 2, 2009 (McClatchy-Tribune Regional News delivered by Newstex) -- Proposed federal efforts to reduce greenhouse gas emissions through "cap-and-trade" programs would raise electricity prices for Wisconsin customers, a group of Midwestern utilities said Wednesday. Under one scenario, rates could jump by as much as 63% from 2012 to 2030, said Midwest Consumer Utilities, a group that includes Madison Gas and Electric Co. and WPPI Energy, which serves 50 customer-owned electric utilities providing power in Wisconsin, Upper Michigan and Iowa. A study commissioned by Midwest Consumer Utilities analyzes the costs under different approaches to cap-and-trade. Such programs place an overall limit -- the cap -- on pollutant emissions. Companies then get individual emission allowances, either through an auction or direct allocation. If they reduce their emissions below the allowance level, they reap pollution credits they can sell to other firms. President Barack Obama and Democratic lawmakers advocate cap-and-trade, while some Republicans have denounced it as leading to sharply higher energy prices.
