: These can be replaced in a relatively short period of time. Major examples include: Hydroelectric : Energy from flowing water. : Sunlight converted into heat or electricity. Geothermal : Thermal energy from beneath Earth's surface. : Kinetic energy from moving air.
Sunlight converted into usable energy (active vs. passive).
Which energy resource currently supplies most of the world's energy? Fossil fuels (coal, oil, and natural gas). Why is solar energy considered an intermittent resource?
: Chemical energy stored in wood, peat, and agricultural waste. Section 15.3 Questions & Answers section 15.3 energy resources answer key pdf

Replenished naturally in short time | | Nuclear fission | D. Splitting atomic nuclei | | Hydroelectric | B. Energy from flowing water | | Geothermal | F. Heat from Earth’s interior |
Water pumped below ground is converted to steam by Earth's internal heat. Wind: Kinetic energy of moving air turns a turbine.
Answer: b) Reducing energy consumption through reduced usage or more efficient use of energy resources
Formed from the remains of ancient plants and organisms. Examples include coal, oil (petroleum), and natural gas.
Formed over millions of years from the remains of ancient plants and animals.
