electrical energy that does not pollute the atmosphere, water, or earth. Geothermal energy comes from the heat generated deep within the Earth’s core. Geothermal reservoirs can be found at tectonic plate boundaries near volcanic activity or deep underground. Geothermal energy can be harnessed by drilling wells to pump hot water or steam to a power plant . This energy is then used for heating and electricity. kinetic energy produced by the movement of air, able to be converted to mechanical power.

Renewable resources are an energy source that cannot be depleted and are able to supply a continuous source of clean energy. energy resources that are exhaustible relative to the human life span, such as gas, coal, or petroleum. gas in the atmosphere, such as carbon dioxide, methane, water vapor, and ozone, that absorbs solar heat reflected by the surface of the Earth, warming the atmosphere. able to convert solar radiation to electrical energy. Gina Borgia, National Geographic Society Jeanna Sullivan, National Geographic Society Tyson Brown, National Geographic Society National Geographic Headquarters 1145 17th Street NW Washington, DC 20036 Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol . Biomass can be used as a source of energy because this organic material has absorbed energy from the Sun. This energy is, in turn, released as heat energy when burned. Wind energy generates electricity by turning wind turbines. The wind pushes the turbine’s blades, and a generator converts this mechanical energy into electricity. This electricity can supply power to homes and other buildings, and it can even be stored in the power grid . There are some challenges associated with using renewable resources. For instance, renewable energy can be less reliable than nonrenewable energy, with seasonal or even daily changes in the amount produced. However, scientists are continually addressing these challenges, working to improve feasibility and reliability of renewable resources. Solar, wind, hydroelectric, biomass, and geothermal power can provide energy without the planet-warming effects of fossil fuels. group of cells that converts sunlight into electricity. rate of producing, transferring, or using wind energy, usually measured in watts. massive slab of solid rock made up of Earth's lithosphere . Also called lithospheric plate. living organisms, and the energy contained within them. network of cables or other devices through which electricity is delivered to consumers. Also called an electrical grid. Renewable energy comes from sources that will not be used up in our lifetimes, such as the sun and wind. Twitter Facebook Pinterest Google Classroom Email Print Encyclopedic Entry Vocabulary When it comes to energy resources, there is always the question of sustainability. It is important that resources provide enough energy to meet our needs—to heat our houses, power our cities, and run our cars. However, it is also important to consider how these resources can be used long term. Some resources will practically never run out. These are known as renewable resources. Renewable resources also produce clean energy , meaning less pollution and greenhouse gas emissions, which contribute to climate change. Join our community of educators and receive the latest information on National Geographic's resources for you and your students. Radiation from the Sun can be used as a power source as well. Photovoltaic cells can be used to convert this solar energy into electricity. Individually, these cells only generate enough energy to power a calculator, but when combined to create solar panels or even larger arrays, they provide much more electricity. resource that can replenish itself at a similar rate to its use by people. Coal, one of humankind’s earliest fuel sources, is still used today to generate electricity. However, renewable energy sources articles over time, there has been a shift in demand for cheaper and cleaner fuel options, such as the nonrenewable energy source of natural gas, and renewable options like solar power and wind energy. Each energy resource has its advantages and disadvantages. Explore nonrenewable and renewable options with this collection on energy resources. the rate of producing, transferring, or using geothermal energy, usually in the form of electricity. Searching for the right method of using renewable resources is a task that is growing ever more important as the Earth’s supply of nonrenewable resources continues to dwindle. Converting to renewable energy will not only better sustain the world’s rapidly growing population, but it will also provide a cleaner, healthier environment for the generations to come. Geothermal power is a form of renewable energy created by powering electrical generators with the heat of the earth and naturally occurring subterranean hot water reservoirs. industrial facility for the generation of electric energy. instrument that generates power from the force of wind rotating large blades. renewable energy derived from living or recently living organisms, mostly plants.

Coal, one of humankind’s earliest fuel sources, is still used today to generate electricity.

Each energy resource has its advantages and disadvantages. Explore nonrenewable and renewable options with this collection on energy resources. energy obtained from sources that are virtually inexhaustible and replenish naturally over small time scales relative to the human life span. The United States’ energy sources have evolved over time, from using wood prior to the nineteenth century to later adopting nonrenewable resources, such as fossil fuels, petroleum, and coal, which are still the dominant sources of energy today. But the Earth has a limited supply of these resources. Recently, renewable resource use has begun to increase. According to the U.S. Environmental Protection Agency, 11 percent of the U.S. energy consumption came from renewable resources in 2017.

Also known as hydroelectricity. Hydropower is one of the oldest renewable resources and has been used for thousands of years. Today, every U.S. state uses some amount of hydroelectricity. With hydropower, the mechanical energy from flowing water is used to generate electricity. Hydroelectric power plants use the flow of rivers and streams to turn a turbine to power a generator, releasing electricity. Solar, wind, hydroelectric, biomass, and geothermal power can provide energy without the planet-warming effects of fossil fuels. energy made available by a flow of electrical charge, through a conductor. Electrical energy is measured in Joules.
