Electricity production is the largest energy-related source of CO2 emissions in the world, with coal being one of the leading contributors. Luckily, there are more than ten renewable sources that can provide electricity to power homes and businesses. Solar, wind, hydroelectricity, geothermal heat pumps, and biomass are just a few examples of clean energy sources which produce little or no greenhouse gases while generating electricity for consumers. The following list includes 10 top options among these renewable resources: 1. Solar energy – Solar energy is derived from the sun’s radiation and can be used for heating, cooling, or generating electricity. There are several ways to capture solar energy, including using photovoltaic cells to convert sunlight into electricity, using solar thermal collectors to heat water or air, or using passive solar design principles to increase the efficiency of buildings. https://colorviewfinder.co/solar-switch/ 2. Wind energy – Wind turbines use the wind’s kinetic energy to generate electricity. Wind power has grown rapidly in recent years as technology has improved and costs have decreased. In some areas, wind power accounts for a significant percentage of total electricity generation. 3. Hydroelectricity – Hydroelectricity is produced by harnessing the potential energy in water as it falls, runs through a turbine or dam. In 2011, the five countries with the largest installed electricity capacity from hydropower were China, Brazil, Canada, the USA, and Russia. 4. Biomass – This renewable energy source harnesses heat from the sun trapped by plants to grow and release stored solar energy in a process known as photosynthesis. Biomass can be used for heating and power generation via biomass combustion. It may also be used directly for mechanical power such as moving vehicles or turning turbines to generate electricity. 5. Geothermal energy – The Earth’s internal heat is constantly dissipating into space at a rate of 47 terawatts according to some estimates (almost ten times that of man-made global warming). Geothermal energy taps into this heat by drilling deep wells into the Earth’s surface and extracting the heated water, which can be used to generate electricity or heat homes and businesses. 6. Solar thermal – This technology uses mirrors to concentrate sunlight onto a receiver, heating the fluid inside. The heated fluid can then be used to power turbines and generate electricity, just like with hydro and geothermal power plants. 7. Wave and tidal – Tidal power take advantage of the gravitational pull of the moon and sun on the oceans’ water. Several tidal barrages and ocean-based turbines have been built around the world, but the high cost and environmental impacts have slowed down deployment. Wave power captures the energy in waves and uses it to power turbines. While several devices have been developed, the technology is still in its early stages and has yet to be widely deployed. 8. Wind power – See above 9. Biogas – Biogas is created through the anaerobic digestion of biomass, such as manure, municipal waste, or agricultural waste. The biogas can be burned directly to generate heat or electricity, or it can be processed into methane for use in natural gas pipelines. 10. Fuel cells – A fuel cell is a device that converts the chemical energy from a fuel into electrical energy by breaking down molecules of hydrogen or hydrocarbons into electrons and protons. Fuel cells can run on a variety of fuels, including natural gas, methanol, ethanol, and hydrogen. ConclusionThe following are the 10 top renewable energy sources that produce little or no greenhouse gases while generating electricity for consumers. Solar, wind, hydroelectricity, biomass, geothermal energy, and solar thermal power are some of the most popular forms of this type of clean energy.
