托福official21阅读第1篇Geothermal Energy题目解析

Geothermal energy is in a sense not renewable, because in most cases the heat would be drawn out of a reservoir much more rapidly than it would be replaced by the very slow geological processes by which heat flows through solid rock into a heat reservoir. However, in many places (for example, California, Hawaii, the Philippines, Japan, Mexico

Geothermal Energy Basics | NREL

Geothermal Basics

U.S. Geothermal Growth Potential. The 2019 GeoVision analysis indicates potential for up to 60 gigawatts of electricity-generating capacity, more than 17,000 district heating systems, and up to 28 million geothermal heat pumps by 2050. If we realize those maximum projections across sectors, it would be the emissions reduction equivalent of taking 26 million cars off U.S. roads

Geothermal energy

Geothermal energy is heat from the Earth. It is a renewable energy source with multiple applications including heating, drying and electricity generation. How is geothermal energy produced? Geothermal systems extract the Earth''s heat in the form of fluids like steam or water. The temperatures achieved determine the possible uses of its energy

What Is Geothermal Energy? Definition and How It Works

Geothermal energy is not only cleaner, but more renewable than traditional sources of energy like coal. This means that electricity can be generated from geothermal reservoirs for longer and with

Geothermal energy

OverviewSustainabilityHistoryResourcesGeothermal powerGeothermal heatingTypesEconomics

Geothermal energy is considered to be sustainable because the heat extracted is so small compared to the Earth''s heat content, which is approximately 100 billion times 2010 worldwide annual energy consumption. Earth''s heat flows are not in equilibrium; the planet is cooling on geologic timescales. Anthropic heat extraction typically does not accelerate the cooling process.

What is Geothermal Energy? | Microsoft Sustainability

Renewable: Unlike fossil fuels, geothermal energy renewable reservoirs within the earth are naturally replenished and will last billions of years. Reliable and stable: Unlike wind and solar power, geothermal energy is always available and doesn''t fluctuate. Management can accurately predict the power output from geothermal power plants, which
