Renewable Energy Sources
Solar, Biomass, Hydropower, Wind, Geothermal
Non-Renewable Energy Sources
Oil, Nuclear, Natural Gas, Coal
Made from decomposing plants and animals.
Fossil Fuels
Are found in Earth’s crust and contain carbon and hydrogen, which can be burned for energy.
Fossil Fuels
It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion. Takes millions of years to develop and there is a limited amount of it, it is a nonrenewable resource.
Coal
_____ is largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the ______.
Coal, U.S.
It was formed many thousand years ago when the Earth’s climate was radically different.
Oil
Formed from dead plants and animals were crushed under the Earth as more layers of ground fell on top of them. The heat and weight of the layers of soil created the perfect conditions for it’s formation.
Oil
It provides warmth for cooking and heating, and it fuels power stations that provide electricity to homes and businesses. It also fuels many industrial processes that produce materials and goods ranging from glass to clothing, and it is an important ingredient in products such as paints and plastics.
Natural Gas
Often considered a cleaner- burning fuel, primarily due to its higher hydrogen-to-carbon ratio, which results in lower carbon dioxide emissions per unit of energy generated
Natural Gas
A form of energy released from the nucleus, the core of atoms, made up of protons and neutrons.
Nuclear Energy
A cycle where the heat generated by the reactor converts water into steam, which spins a turbine and a generator.
Rankine Cycle
Uses the sun’s light and heat to
generate renewable or ‘green’ power.
Solar Energy
When the sun’s rays hit the cells, it loosens _______ from their atoms. This allows the _____ to flow through the cell and generate electricity.
Electrons
It is the heat energy from the earth
Geothermal Energy
