Al Gore may be a visionary, but he’s right. His plan is reasonable and achievable. We could meet the electric power requirements of the United States, estimated at 250 Gigawatts, GW, of generating capacity with wind turbines and photovoltaic solar arrays, for about $925 Billion in 10 years.

  • Land Based Wind: 100 GW, or 40%, at $2.0 Billion per GW: $200 Billion.
  • Offshore Wind: 100 GW, or 40%, at $4.0 Billion per GW: $400 Billion.
  • PV Solar: 50 GW, or 20% at $6.5 Billion per GW: $325 Billion.
  • Total Cost: $925 Billion. (less than has been squandered on the war in Iraq.)
  • Saving the earth: Priceless.

Key Benefits:

  • Good Jobs.
  • Healthy Economy.
  • Enhanced Emergency Response Capability.
  • Stronger National Security.
  • Clean Environment.
  • No Toxic Wastes.
  • No Mercury.
  • No Radioactive Wastes.
  • No Coal Mining Disasters.
  • Less Government Regulation.

This plan doesn’t exploit solar thermal, marine kinetic, geothermal, deep geothermal, cogen, biofuels, or conservation, which will be integrated into this plan in the near future. The plan also focuses on current electricity demand. It does not yet forecast increased electricity demand from population growth, transition from fossil fuels for heating or cooking, or increased reliance on plug-in hybrid cars.

Clean and Green By 2018!

Wired Gets It Wrong - Nuclear Power is Not Good For the Planet

Hummers: Illogical, Un-Economical, and Bad for The Environment. But They Sure Are Big!

Spencer Reiss, writing in Wired Magazine says “Nuclear Power is The Most Climate Friendly Insdustrial Scale Form of Energy“. Forgetting for a moment that nuclear power requires fuel, waste management, national security infrastructure, massive government subsidies, including artificial limits to liability, nuclear releases tremendous amounts of heat into the environment, and new nuclear are estimated to cost about 2 to 4 times the price of new wind facilities, without cost overruns (and cost overruns are a given with nuclear power plants) and take 10 to 12 years.

The climate friendly industrial scale forms of energy are Solar, Offshore Wind, large scale Marine Kinetic - tapping the Gulf Stream, Deep Geothermal, CoGen, and the NegaWatts available via conservation. Just as a screw can propel a ship thru the water, a screw anchored to the ocean floor will spin because of currents, and can power turbines. Marine Current Turbines, Ltd., based in Bristol, England has just completed the world’s first megawatt scale tidal/marine current driven power plant in the Strangford Narrows in Northern Ireland. If with wind, the sky’s literally the limit, with MCT the sea’s the limit. Geothermal exploits temperature differentials for heating and cooling. Deep Geothermal would use the earth’s heat in abandoned mines and wells to generate steam for industrial process power. Recycled Energy Development, RED, of Westmont, Il does CoGen. RED captures industrial waste energy to produce electricity and thermal power, often without burning any additional fuel or emitting any additional pollution. For industrial partners, RED reduces energy costs substantially, increases reliability, and offers the opportunity for emissions credits. Akeena, Evergreen Solar, First Solar, Sunpower, World Water and Solar, and Vestas Wind are old news. Ausra develops and deploys utility-scale solar thermal technologies to serve global electricity needs in a dependable, market competitive, environmentally responsible manner.

Wired Magazine also published a companion piece by Matt Power that says “Pound for pound, making a Prius contributes more carbon to the atmosphere than making a Hummer” (click here). The fallacy here is that they forget to mention that a Hummer weighs about three times more than a Prius, so to have an honest statistic you need to compare 3 pounds of Hummer to each pound of Prius. They do note that the operating efficiency of the Prius outweighs any manufacturing inefficiency. And they point out that it is better for the planet to buy a used car than a new car.
