Which U.S. state produces the most wind power?

In addition to crude oil and natural gas, Texas is also the biggest wind producer with turbines capable of producing more than 32,000 megawatt hours of electricity. Texas sits at the bottom end of what is known as the “wind belt”—Midwestern states with consistently strong wind potential.

Which of the following can be used to store excess renewable energy?

Renewables like wind and solar power are intermittent. Storing the excess energy they produce means we can use it at night or during periods when the wind isn’t blowing. Numerous energy storage solutions are currently being tested and deployed around the world.

Which of the following is NOT part of a solar thermal power collector?

Unlike photovoltaic (PV) solar, solar thermal systems do not use semiconductors to convert sunlight directly into electricity. Instead, they use reflectors to focus sunlight onto a liquid, which then turns to steam and drives a turbine that produces electricity. Not surprisingly, these systems are usually built in the desert.

Which public figure recently added PV solar panels to his or her residence?

President Obama gave the go-ahead for solar panels on the roof of the White House to assist with water heating and electricity. The cost of solar power systems has dropped dramatically over the last decade and the White House project is expected to pay for itself in just eight years.

What country produces the most geothermal powered electricity?

With more than 3,000 megawatts of capacity, the United States is the world leader in geothermal power production. However, Iceland supplies 30 percent of its total electricity via geothermal, compared to only 0.3 percent in the U.S.

Which of the following provides the largest percentage of renewable energy supply in the U.S.?

In use since the late 1800s, Hydroelectric power provides the majority of renewable power in the United States—more than 60 percent. Developments in micro systems are now allowing additional capacity to come on line without the need for additional dams and reservoirs.

Which of the following can be used to harness renewable marine energy?

Marine energy—sometimes called ocean power—is one of the most abundant renewable resources on the planet. Many different technological designs are currently in development to bring this energy onto land.
