Nonrenewable Energy
Energy sources that cannot be replenished or regenerated within a human lifespan, such as fossil fuels like coal, oil, and natural gas.
Greenhouse Gases
Gases in the Earth's atmosphere that trap heat and contribute to global warming, including carbon dioxide, methane, nitrous oxide, and fluorinated gases.
Hydroelectric Power
Electricity generated by converting the energy of flowing or falling water into electricity using turbines and generators, a widely used form of renewable energy.
Nuclear Power
Electricity generated through nuclear reactions, either splitting atomic nuclei (nuclear fission) or combining them (nuclear fusion), to produce heat for electricity generation.
Renewable Energy
Energy sources that can be naturally replenished within a human lifetime, such as solar power, wind power, hydropower, geothermal energy, and biomass.
Biomass Energy
Use of organic materials like plants and animal waste to produce heat or electricity, a renewable energy source that helps reduce greenhouse gas emissions.
Climate Change
Long-term shifts in temperature and weather patterns globally, primarily caused by human activities like burning fossil fuels and deforestation, leading to increased greenhouse gas concentrations.
Coal
Combustible sedimentary rock made mostly of carbon, formed from the remains of plants millions of years ago, a nonrenewable energy source.
Petroleum
Naturally occurring liquid mixture composed mainly of hydrocarbons, known as crude oil, formed over millions of years from marine organisms' remains, a nonrenewable energy source.
Solar Power
Harnessing sunlight to convert it into usable electrical or thermal energy using solar panels or collectors, a renewable energy source.
Wind Power
Conversion of wind energy into electricity using wind turbines, a renewable energy source that harnesses the natural force of the wind to generate power.
Natural Gas
Fossil fuel mainly consisting of methane, formed deep beneath the Earth's surface and often found alongside oil deposits, a nonrenewable energy source.
