What Is Green Power? Green power is electricity generated from renewable sources such as geothermal, solar, and wind biomass, energy, and hydroelectricity with minimal impact. It is available to consumers in markets that are deregulated who want to support cleaner energy sources by paying an additional cost to their utility bills. Many renewable energy sources are less damaging to the environment than drilling for oil or mining coal. They can also aid in reducing greenhouse emissions of greenhouse gases. Solar Energy Solar energy is one of the most popular green energy sources. Solar energy is a renewable source because it is never depleted. It is an efficient, clean and safe energy source that helps reduce greenhouse gas emissions as well as pollution of the air from fossil fuels, such as coal, natural gas and oil. This energy is a great alternative to nuclear power that requires mining extraction, storage and storage of radioactive waste. Solar thermal collectors, photovoltaic panels and concentrated solar thermal energy (CSP) are all methods to harness the sun's power. Solar power can be delivered directly to homes and businesses or to grids that supply electricity to other. Some customers can sell surplus energy to a utility company. This can lower the cost of electricity and offset rising utility costs. All types of solar energy create zero emissions of pollutants or air, unlike fossil fuels that generate carbon dioxide and other harmful gases during their combustion. Solar energy can also be utilized to power other kinds of devices, like satellites, boats and spacecrafts in areas where accessing the electricity grid is not feasible or even possible. On a smaller scale solar can also be used to power buildings. Many homeowners install PV cells on their roofs to produce electricity. Passive solar homes allows for these homes to take advantage of the sun's warmth throughout the day and keep it at night. Solar-powered houses also benefit from needing minimal maintenance. Hydropower is a type of solar energy that makes use of the natural flow in streams, rivers, and dams. Hydropower, just like biomass and wind, is a renewable resource as it can be replenished. If you are looking to add hydropower to your business or home look into EPA's list of third-party certified options. Geothermal Energy A geothermal plant uses heat from the Earth to produce electricity. The process makes use of hot water and steam which naturally occur just a few kilometers beneath the surface of the Earth. It is a renewable and sustainable energy source that produces electricity all day long all year round. Geothermal energy can help reduce our dependence on fossil fuels, and is one of the most eco-friendly methods of energy generation. The most popular geothermal power station is the flash-steam plant. This makes use of water heated to 182deg C or 360deg F to generate electricity from turbines and power plants. Steam can be used to heat industrial processes and buildings. Iceland, for instance, relies on the geothermal power to melt snow and heat its streets, sidewalks and parking areas during the frigid Arctic Winter. A hot dry rock power plant is an additional geothermal source of energy. It taps underground reservoirs that are made up of hot, dry rock that has been heated by either natural processes. HDR plants are simpler to construct and operate since they require less infrastructure. According to greenpower electric scooters , there are enough HDR resources available in the United States for all of our current electrical requirements. Geothermal power stations that produce steam can be used as a source of power by using a steam turbine generator or combined with a gas fired turbine to increase efficiency. The resulting mixture can then be converted into natural gas, which is burned in a conventional boiler to produce electricity. In addition to being safe and reliable, geothermal energy also has the smallest carbon footprint of all renewable energy sources. Binary-cycle plants that utilize an engine to convert steam into electricity create very little or no nitrous dioxide, methane, and sulphur oxide. However, despite its advantages geothermal energy doesn't come without its difficulties. The drilling needed to build geothermal power plants could trigger earthquakes and could cause groundwater pollution. Injection of high-pressure water streams into geothermal reservoirs could cause subsidence. This is a gradual sinking that could damage roads, structures, and pipelines. Biogas Biogas is an energy source made of renewable gaseous substances that generates green energy. It can be produced from manure, agricultural waste plant material such as municipal waste, sewage, food waste and other organic waste materials. Biogas can be used to create electricity, heat, and also heat and power, or it can be transformed into fuels for transport using the Fischer-Tropsch process. Biogas can also be used to produce renewable hydrogen which is used in fuel cells. Fuel cells are expected to play a major role in the future energy systems of the world. The most popular method of valorising biogas is to generate electricity using a combined heat and power (CHP) plant. The heat generated by the CHP plant is used to fuel the fermentation of organic wastes. In turn, the electricity is then fed back to the grid. Alternatively, it can be compressed into natural gas, and then incorporated into existing natural gas distribution networks. Biogas can also be used as a replacement for imported natural gas in commercial, ground transportation and residential constructions. In addition to providing renewable energy, biogas can also help reduce carbon dioxide emissions and pollution from conventional cooking. The CCAC is working to develop instruments for measuring, reporting and verification (MRV) of the clean cooking practices within communities and households in low- to middle-income countries, to help the 67 countries that have incorporated clean cooking goals in their Nationally Determined Contributions (NDCs). Biogas can be used as a substitute for traditional natural gas for heating and cooling and to substitute fossil fuels in electricity generation carbon dioxide emissions will be reduced. Biogas is also a viable substitute for oil, coal, and other fossil fuels for production of liquid transportation fuels. By collecting and recovering methane by capturing and recovering methane, we can stop the release of greenhouse gasses into the atmosphere and the runoff of nitrogen which would otherwise pollute our water sources. The Plessis-Gassot non-hazardous waste landfill in Claye-Souilly, France, for instance collects biogas and converts it into a sustainable supply of energy for the households that are connected to the system. Additionally small-scale biogas plants could be constructed in cities to allow for the collection and use of organic waste that is generated locally, avoiding greenhouse gases that are generated by the transportation and treatment of these materials. Hydroelectric Power Hydropower makes use of the kinetic energy of flowing water to generate electricity. It is the largest and most affordable renewable energy source in the world. address here does not emit direct greenhouse gases but it does have significant environmental effects. It is a flexible form of green energy that can be adjusted to meet changing demand and supply. It is able to last a life of over a hundred years and is able to be upgraded to improve efficiency and performance. Most traditional hydropower plants harness the energy of falling waters by using dams. The kinetic energy of the water is converted into electricity by the turbines that spin at a speed proportional to the velocity of the water. The electricity is then transmitted to the grid to be used. Hydroelectric power plants require an enormous investment in reservoirs and pipes. However the operating costs are minimal. Furthermore, these plants can be used as backups to other intermittent renewable power sources like solar and wind. There are two major kinds of hydroelectric plants that are run-of-river and storage. Storage plants are characterized by huge impoundments that hold more than a season's supply of water. Run-of-river facilities have a small impoundment and draw water from flowing rivers or streams. Hydropower facilities are typically located in or near concentrations of population, where there is a high demand for electricity. The environmental impact of hydropower is dependent on the size and location of the dam, the amount of water displaced as well as the wildlife and habitat affected by inundation and decomposition. The effects of hydropower can be mitigated and reduced through the use of Low Impact Hydroelectricity Standards (LIHI) for the construction and operation of hydropower projects. The standards provide measures to protect river flows as well as water quality passage for fish and protection, aquatic ecosystems, watershed protection, endangered and threatened species, recreation, and cultural resources. Certain hydropower plants are the largest in the world “batteries” because they produce renewable energy by pumping water from a lower pool uphill to a bigger reservoir. When there is a demand for electricity the water in the lower reservoir is released to power generators, whereas the water in the higher reservoir is pumped back downhill through turbines to generate more electricity.
