Energy Crisis – What Can We Do

June 14th, 2008 · Comments Off on Energy Crisis – What Can We Do

As energy and food prices set new world records, what can we do at home to avert the crisis? Food prices are rising because corn is diverted from food production to producing ethanol for use as fuel in motor vehicles and is exacerbated by the recent flooding in the Mid West. Oil prices continue to […]

Hostage to Oil

September 21st, 2007 · 1 Comment

Without greater investment into solar and hydrogen energies, we are held hostage to rising oil prices. Alternative energies such as solar and hydrogen fuel cells offer tremendous potential to provide energy independence and energy security. The dependence of the U.S. upon imported foreign oil raises inflation, weakens our currency, exacerbates the trade deficit, and forces […]

Solar Efficiency

September 17th, 2007 · Comments Off on Solar Efficiency

There is considerable variance in calculating the cost of solar energy. Using U.S. Solar Radiation Resource Maps from the National Solar Radiation Data BaseThe (NSRDB) we found the amount of kilowatt-hours (KWH) per days of solar radiation per square-meter varies from less than two for Northern Alaska to six KWH/m2 per day for parts of […]
