What is clean energy
Clean energy refers to energy produced from sources that do not emit pollutants typically associated with burning fossil fuels, which are the primary contributors to greenhouse gas emissions and environmental pollution. The term encompasses a variety of generation methods, including renewable resources and technologies that have minimal impact on the environment. Examples of clean energy sources include:
1. Solar power: Energy harnessed from sunlight using photovoltaic cells or solar thermal collectors.
2. Wind power: Energy generated by capturing the kinetic energy of wind with turbines.
3. Hydroelectric power: Electricity produced from the gravitational force of falling or flowing water.
4. Geothermal energy: Energy derived from the Earth's internal heat.
5. Biomass: Energy produced from organic materials, such as plant and animal waste, while ensuring that the consumption does not outpace the replenishment rate.
6. Tidal and wave power: Energy generated by the movement of sea water caused by tides and waves.
Clean energy is considered essential for combating climate change and reducing the environmental impacts of energy production and consumption. It is also seen as a sustainable alternative to traditional fossil fuels (coal, oil, and natural gas) because it relies on sources that are naturally replenished. Investing in clean energy not only helps to preserve the environment but also supports energy independence and the development of a low-carbon economy.
