What is the main source of biomass energy?

1

How do the pulp and paper industries utilize waste wood?

1

Can biomass be made into cleaner-burning transportation fuels?

1

Can alcohol fuels made from biomass be domestically produced?

1

What is produced when 10 percent ethanol is mixed with gasoline?

1

What is the benefit of burning biomass in a waste-to-energy plant?

1

What technologies do waste-to-energy plants use to reduce emissions and odors?

1

Geothermal energy comes from heat within the Earth.

1

Examples of geothermal energy are hot springs, volcanoes, and geysers.

1

Geothermal energy is generated in Earth’s core, which is made of magma (molten iron) surrounding a solid, mostly iron core.

1

Red hot temperatures are maintained inside the Earth because of the slow decay of radioactive particles found in all rocks, and the immense pressure on the core.

1

Geothermal energy is renewable. The hot water used by power plants is replenished by precipitation and the geothermal heat is continually produced.

1

Wells can be built to pump super-heated water to the surface.

1

Geothermal energy is used to produce electricity and to heat and cool buildings.

1

Geothermal energy was used by ancient people for heating and bathing. Hot springs are said to have therapeutic effects today.

1

In 1904, the Italians first used steam erupting from the earth to power a turbine generator.

1

Dry steam reservoirs are the most efficient for producing electricity, but they are very rare.

1

The United States generates more electricity from geothermal than any other country in the world.

1

High temperature geothermal resources capable of producing electricity are not economically available in all parts of the nation.

1

The most active geothermal resources are found along major tectonic plate boundaries, where magma comes very near Earth’s surface.

1

Geothermal energy produces less than one percent of the electricity consumed in the nation today.

1

Geothermal energy does little damage to the environment because geothermal power plants sit on or near the geothermal reservoirs and do not burn any fuel.

1

Geothermal steam and hot water contain traces of hydrogen sulfide and other gases, as well as chemicals that are harmful at high concentrations.

1

The gases and chemicals from geothermal power plants are usually reinjected into the Earth.

1

The temperature of the earth a few feet underground remains constant year round—about 52 degrees Fahrenheit in moderate climates.

1

Low temperature geothermal energy is available everywhere in the U.S. for heating and cooling homes.

1

Geothermal heat pumps use the Earth’s constant temperature as an energy source to heat buildings in winter and cool them in summer.

1

Moving water has been used as a source of energy for thousands of years.

1

Hydropower is considered one of the cleanest and cheapest energy sources in widespread use today.

1

Moving water is a renewable energy source.

1

Moving water can turn a turbine to generate electricity.

1

Hydropower was first used to turn water wheels to grind grain.

1

Hydroelectric power is reliable because dams can be built to store water. Controlling the flow of the stored water allows a power plant to operate in all weather conditions and at times of greater electrical demand.

1

About what percentage of total U.S. electricity is generated by hydropower plants, depending on the amount of rainfall?

1

Hydropower provides the U.S. with about what percentage of our total energy consumption?

1

In the last 60 years, hydropower production in the United States has increased by 63 percent.

1

The nation's largest producer of hydroelectric power is the Federal Government, which operates many large dams and power plants.

1

How many hydroelectric power dams are there in the U.S. today?

1

How many dams in the U.S. do not have generating plants on them?

1

New construction and improvements at existing hydropower plants could increase our hydroelectric capacity by how much MW by 2025?

1

When a hydropower dam is built, thousands of acres of nearby land are flooded to create a reservoir.

1

Projects using wave and tidal energy to generate electricity are being tested and used in a few locations in the U.S. and around the world.

1

Dams can disturb the migration and spawning of fish populations in the river.

1

Dams can alter the natural flow of the river and change the amount of water that reaches communities downstream.

1

Reservoirs that result from construction of a dam are often developed for recreational purposes, such as boating and fishing.

1

The use of conventional hydropower in the U.S. is not expected to increase significantly in the future, but wave and tidal projects are expected to increase.

1

Which country produces 96 percent of its electricity from hydropower?

1

Hydropower has which four main factors associated with it?

1

What is wind?

1

Do wind turbines cause air or water pollution?

1

Is wind a renewable source of energy?

1

How often do wind turbines operate on average?

1

What were windmills used for in the past?

1

What do wind turbines have to harness wind's kinetic energy?

1

How much of the wind's kinetic energy can wind plants convert into electricity?

1

What must be used to generate electricity when the wind is not blowing?

1

What are good locations for wind farms?

1

Do offshore turbines produce more electricity than turbines on land?

1

1

Where can wind turbines be used?

1

Does every state have the capacity to produce electricity from wind?

1

How much of the world's wind energy does the U.S. generate?

1

Are older wind turbines noisy?

1

What can wind turbines potentially injure?

How much does it cost to produce electricity from wind power plants compared to the average cost of electricity in the U.S.?

1

How many homes can wind turbines power in the U.S.?

1

Do offshore turbines cost more money to build and operate than turbines on land?
