Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less and better sources of energy for continuous service) or changing one's behavior to use less and better source of service (for example, by driving…

Energy policies are the government's strategies and decisions regarding the production, distribution, and consumption of energy within a specific jurisdiction. Energy is essential for the functioning of modern economies because they require energy for many sectors, such as industry, transport, agriculture, housing.

China is the world's top electricity producer from renewable energy sources. China's renewable energy capacity is growing faster than its fossil fuels and nuclear power capacity.

An energy crisis or energy shortage is any significant bottleneck in the supply of energy resources to an economy. In literature, it often refers to one of the energy sources used at a certain time and place, in particular, those that supply national electricity grids or those used as fuel in industrial development.

Renewable energy in the United Kingdom refers to energy from renewable sources used for electricity generation, heat and transport in the United Kingdom. In 2024, renewables accounted for 50.4% of UK electricity generation and 16.2% of gross final energy consumption.
