What is Geothermal Energy?

Geothermal Energy is energy generated from heat in the Earth’s core.

Geothermal power plants use resources that have water and heat. They

require high temperature hydrothermal resources of 300ºF to 700ºF that

come from dry steam wells or hot water wells. These resources are used by

drilling wells into the ground and creating pipes to bring the steam or hot

water to the surface.

Types of Geothermal Power Plants

Dry steam plants directly use geothermal steam to turn turbines.

Flash steam plants are the most commonly used power plant. They take high-pressure hot water from inside the earth and convert it to steam to drive the turbines of the generator. When the steam is converted back into water, it is put

back into the ground so it can be reused.

Binary cycle power plants transfer heat from geothermal hot water to another liquid. The second liquid turns to steam and turns the turbine of the generator.

Why Pick Geothermal Energy?

FINANCIAL BENEFITSFINANCIAL BENEFITSThe cost of the land to build a geothermal power plant on is less expensive than building an oil, gas, coal, or nuclear power plant. This is because geothermal plants take up very little room. No fuel is used to generate the power which means that the running cost for the plants are very low. Also, there are no costs for purchasing, transporting, or cleaning up fuels.

Geothermal energy is renewable, therefore a constants energy source. Since it will never run out, its cost will likely never continue to rise with timeUp to 60% reduction in heating costs. geothermal energy is homegrown, this will create jobs and less reliance on oil producing countriesYou will receive a Hydro-Quebec grant when you have the work done by a contractor accredited by the Canadian GeoExchange Coalition (CGC).

ENVIRONMENTAL BENEFITSENVIRONMENTAL BENEFITS

No greenhouse gasses are emittedEmissions are extremely low

No fossil fuels are burned when extractedReleases less than 1% of carbon dioxide emissionsGeothermal energy is able to supply 75%-100% of commercial energy needed which will significantly reduce the amount of pollution released.

GREEN, SUSTAINABLE ENERGY SOURCE!

Why Pick Geothermal Energy?

RELIABILITYRELIABILITY

Available 24 hours a day, 365 days a yearpower plants have average availabilities of 90% or higher compared to 75% for coal plantsgeothermal energy is very efficient because after site is located and built, efforts required to channel energy is not very hardlong lasting (an underground loop is usually good for 50 years or more and a ground-source heat pump is usually good for about 20 years)easy maintenance (require same amount of maintenance as a conventional forced-air electric heating system)
