Energy Resources and Storage

Synthetic materials are created by humans using chemical reactions to transform natural raw materials into new substances with different properties.

Solar, wind, and hydro-power are all examples of renewable energy sources that are naturally replenished.

Renewable energy comes from sources that are naturally replenished on a human timescale, such as sunlight, wind, and water.

Groundwater is part of the water cycle and can be replenished through precipitation and infiltration within a human lifetime. Fossil fuels and petroleum take millions of years to form.

The Sun provides the vast majority of the energy that drives Earth's climate system, powering atmospheric circulation, ocean currents, and the water cycle. Internal heat from the Earth and human energy generation contribute negligible amounts of energy to the climate system by comparison.

Coal is a fossil fuel that takes millions of years to form from ancient organic matter, meaning it cannot be replenished within a human lifespan once consumed. Sunlight, waves, and wind are renewable resources because they are continuously replenished by natural processes.

Coal is a fossil fuel formed from the remains of ancient plants over millions of years. Because it takes so long to form, it cannot be replaced once it is used up, making it a non-renewable energy source.

Nuclear energy is considered non-renewable because it relies on uranium ore, which is a finite resource mined from the Earth. Biomass, geothermal, and hydroelectric power rely on naturally replenishing resources.

The energy mix is the specific combination of different primary energy sources (such as fossil fuels, nuclear, and renewables) used to meet the energy needs of a country.

Fossil fuels are non-renewable energy resources because they take millions of years to form from ancient organic matter. Once consumed, they cannot be replaced on a human timescale.

Natural gas has been the primary source of electricity generation in the UK for many years. While renewables are growing, gas remains the dominant component of the energy mix.

While wind energy is clean during operation, the manufacturing, transport, and installation of massive turbines require significant energy and materials, which can cause pollution.

Fossil fuels like coal, oil, and gas are formed from the remains of ancient plants and animals that were buried and subjected to heat and pressure over millions of years.

A non-renewable resource is one that does not replenish itself at a rate fast enough for human consumption. Water is considered a renewable resource because it is part of the continuous hydrological cycle.
