Sustainability

A:

Humans use coal in many ways, including as a fuel and as a source of carbon. As a solid fuel, coal burns to provide heat from stoves, furnaces and boilers as well as energy to supply electrical generating plants. Metal refiners use coke, a solid residue from low-sulfur bituminous coal, in purifying metals in blast furnaces.

  • What is hydroelectric energy?

    Q: What is hydroelectric energy?

    A: Hydroelectric energy converts the kinetic energy of flowing water into electricity using a turbine. Water flows through a channel, usually carefully regulated as part of a dam spillway, and it turns the blades of the turbine. As long as water continues to flow steadily, the turbine produces a steady stream of electricity. The U.S. Geological Survey Science School states that 19 percent of the world's electricity comes from hydroelectric energy.
