• Global Warming is a factGlobal Warming is a fact• China and India will soon China and India will soon

surpass U.S.A. in Greenhouse surpass U.S.A. in Greenhouse gas emissiongas emission

• If we do nothing, they will If we do nothing, they will continue to do nothing continue to do nothing ((The EconomistThe Economist 9/9/06) 9/9/06)

• Geothermal energy is the only renewable source of energy which can be tapped round the year and the day with no need of storage facilities– one injection well and one production well.

– cold water is pumped down and circulates through the fractured reservoir

– natural heat exchanger delivers hot and pressurized water to the production wells

– energy is converted into power by means of a turbine-generator unit

– excess heat is used for space heating

– cooled water is then reinjected at depth

– closed-loop system provides CO2-free energy.

The Sleipner project in Norway's North Sea is the world's first commercial carbon dioxide capture and storage project

Started in 1996, it sequesters about one million metric tons of carbon dioxide each year

Can Baking Soda curb Global Can Baking Soda curb Global Warming?Warming?

“Jones, the founder and CEO of Skyonic, has come up with an industrial process called SkyMine that captures 90 percent of the carbon dioxide coming out of smoke stacks and mixes it with sodium hydroxide to make sodium bicarbonate, or baking soda. The energy required for the reaction to turn the chemicals into baking soda comes from the waste heat from the factory.

The system also removes 97 percent of the heavy metals, as well as most of the sulfur and nitrogen compounds, Jones said.”

Goals of Kyoto ProtocolReduction of greenhouse gases to below

1990 levels:5.2% world wide reduction on average by 2008-

2012

6% for Canada by 2008-2012

When sufficient countries ratify the Protocol (at least 55 countries comprising at least

55% of emissions), Protocol comes into effectUSA - 25% of emissions
