TOKYO — World governments must quickly start a $45-trillion “energy technology revolution” that could drive up the cost of producing carbon ten-fold, or risk emissions surging by 2050, the West's energy watchdog warned on Friday.

The world would need to build dozens of nuclear power plants a year and bury carbon emitted from dozens more gas and coal plants, plus cutting the carbon intensity of cars, trucks, buses and planes eightfold, to halve emissions by mid-century, the International Energy Agency said in a new report.

On a sunny june day in 1979, President Jimmy Carter held the first and only press conference on the White House roof. Atop the West Wing, he unveiled a $28,000 solar cell system that captured the sun's energy to provide hot water for the White House. He also launched a sweeping drive aimed at harnessing the sun, the wind, and other renewable resources to generate 20% of America's electricity by 2000.

It didn't happen, of course. The share of electricity produced by solar cell technology in the U.S. last year was a mere 0.07%. Carter's solar water-heating system was removed in 1986 so a leak in the roof could be fixed. The solar panels were supposed to be reinstalled but they never were.

What is Geothermal Energy?

Geothermal energy draws sustainable power from the natural heat of the earth. It is the thermal energy contained in the rock and fluid (that fills the fractures and pores within the rock) in the earth’s crust. It is believed that the ultimate source of geothermal energy is radioactive decay occurring deep within the earth. The presence of volcanoes, hot springs, and other thermal phenomena are surface evidence of our planet’s heat resource. Please login or register to see the full article
