Still, some forms of biomass energy could serve as a low-carbon option under the right circumstances. For example, sawdust and chips from sawmills that would otherwise quickly decompose and release carbon can be a low-carbon energy source. Drilling deep wells brings very hot underground water to the surface as a hydrothermal resource, which is then pumped through a turbine to create electricity.
Geothermal plants typically have low emissions if they pump the steam and water they use back into the reservoir. There are ways to create geothermal plants where there are not underground reservoirs, but there are concerns that they may increase the risk of an earthquake in areas already considered geological hot spots. Some tidal energy approaches may harm wildlife, such as tidal barrages , which work much like dams and are located in an ocean bay or lagoon.
Passive solar homes are designed to welcome in the sun through south-facing windows and then retain the warmth through concrete, bricks, tiles, and other materials that store heat. Some solar-powered homes generate more than enough electricity, allowing the homeowner to sell excess power back to the grid. Batteries are also an economically attractive way to store excess solar energy so that it can be used at night.
Scientists are hard at work on new advances that blend form and function, such as solar skylights and roof shingles. Geothermal technology is a new take on a recognizable process—the coils at the back of your fridge are a mini heat pump, removing heat from the interior to keep foods fresh and cool.
In a home, geothermal or geoexchange pumps use the constant temperature of the earth a few feet below the surface to cool homes in summer and warm houses in winter—and even to heat water. Geothermal systems can be initially expensive to install but typically pay off within 10 years.
They are also quieter, have fewer maintenance issues, and last longer than traditional air conditioners. A backyard wind farm? Boats, ranchers, and even cell phone companies use small wind turbines regularly. Dealers now help site, install, and maintain wind turbines for homeowners, too—although some DIY enthusiasts are installing turbines themselves. Depending on your electricity needs, wind speeds, and zoning rules in your area, a wind turbine may reduce your reliance on the electrical grid.
Wind- and solar energy—powered homes can either stand alone or get connected to the larger electrical grid, as supplied by their power provider. Electric utilities in most states allow homeowners to only pay the difference between the grid-supplied electricity consumed and what they have produced—a process called net metering.
If you make more electricity than you use, your provider may pay you retail price for that power. Advocating for renewables, or using them in your home, can accelerate the transition toward a clean energy future. Contact your power company to ask if it offers that choice. The Ute Mountain Ute tribe is working to free itself from fossil fuel dependency—and preparing to help solarize the rest of the state, too.
Plus, Bernhardt tries to sink offshore wind, and our first-term president takes credit for building a plastics factory that was announced seven years ago. Some people tout bioenergy as a solution to our climate crisis. Two new bills could put the Prairie State on the path to percent renewable energy within decades.
In Texas, tax breaks for fossil fuels outpace tax breaks for renewables by a rate of two to one. Guess which sector is whining about unfairness? With its plan to source all city energy needs from renewable power by , Albuquerque, a winner of the Bloomberg American Cities Climate Challenge, is also jump-starting its solar workforce.
New polls show that all Americans—Democrats, Republicans, and independents alike—want to close the book on our dirtiest fossil fuel. If you want to know where coal is headed, look no farther than Texas—where this dirty fuel is in its death throes. The people and the planet can claim more than a few victories—and is looking better already. The Energy Information Administration offers an abundance of data, maps, graphs and forecasts that can be used to investigate a number of questions.

Total energy production and consumption by state is a clickable map of the U. Tabs at the top of each page contain detailed information on energy in each state. At the time of this writing, the data was from and it's possible that the Energy Information Administration will continue to update this page.

The pulldown menu in the upper left offers further tools for electricity analysis. This is an 'evergreen' source that is updated every year. The report offers trends in energy use, electricity generation, CO 2 emissions, and more. The data includes job creation.
Data from Stanford University. Your Account. Various sources of energy can be used to power human activities, and often this energy must be transferred from source to destination.
Teaching about energy sources is supported by 7 key concepts: 4. There are 6 more fundamental concepts. See them all Industry, transportation, urban development, agriculture, and most other human activities are closely tied to the amount and kind of energy available. The availability of energy resources is constrained by the distribution of natural resources, availability of affordable technologies, socioeconomic policies, and socioeconomic status.
The energy in fossil fuels such as oil, natural gas, and coal comes from energy that producers such as plants, algae, and cyanobacteria captured from sunlight long ago. The energy in biofuels such as food, wood, and ethanol comes from energy that producers captured from sunlight very recently.
Energy stored in these fuels is released during chemical reactions, such as combustion and respiration, which also release carbon dioxide into the atmosphere.
Fuels are often not used at their source but are transported, sometimes over long distances. Fuels are transported primarily by pipelines, trucks, ships, and trains.
Electrical energy can be generated from a variety of energy resources and can be transformed into almost any other form of energy. Electric circuits are used to distribute energy to distant locations. Electricity is not a primary source of energy, but an energy carrier. When a magnet moves or magnetic field changes relative to a coil of wire, electrons are induced to flow in the wire. Most human generation of electricity happens in this way.
Electrons can also be induced to flow through direct interaction with light particles; this is the basis upon which a solar cell operates.
Other means of generating electricity include electrochemical, piezoelectric, and thermoelectric. Examples include batteries, water reservoirs, compressed air, hydrogen, and thermal storage. Storage of energy involves many technological, environmental, and social challenges. A given energy system, from source to sink, will have an inherent level of energy efficiency, monetary cost, and environmental risk.
