What Is Green Power? Green power is electricity generated from renewable resources like geothermal, solar, wind and some forms of biomass and hydroelectricity that is low-impact. Customers who are in markets that are not regulated can add a small amount to their utility bills to help support renewable energy sources that are cleaner. Renewable energy sources are generally less harmful to the earth than oil drilling or coal mining. They can also reduce greenhouse gas emissions. Solar Energy Solar energy is one of the most popular green power sources. Solar is considered renewable because it will never be depleted. It is a clean, efficient and safe energy source that helps reduce greenhouse gas emissions as well as pollution of the air from fossil fuels such as natural gas, coal, and oil. This energy is also a good alternative to nuclear power, which requires the mining and extraction of uranium as well as long-term radioactive waste storage. The sun's radiation can be utilized to generate electricity in a variety ways that include photovoltaic (PV) panels and concentrated solar-thermal power (CSP), and solar thermal collectors. Solar power can be delivered directly to businesses and homes or to grids that supply power to other. Some customers can sell their excess energy to the utility company. This could help lower the cost of electricity and offset rising utility costs. All types of solar energy create no air emissions or pollutants, unlike fossil fuels that produce carbon dioxide and other harmful gases during their combustion. Solar energy can be used to power satellites, spacecraft, boats, and other devices that are located in areas where access to the grid is difficult or impossible. Solar power can be utilized in smaller structures. Many homeowners use PV solar panels on their roofs in order to generate electricity, and passive solar home design lets these homes take in sun's rays during the day to provide warmth, and then store it at night. Solar-powered homes also benefit from the fact that they require very little maintenance. Another type of solar power is hydropower, which uses the natural flow of the water in streams, rivers and dams to produce electricity. Hydropower, similar to biomass and wind, is a renewable resource because it can be replenished. Look through the EPA's list of third party certified hydropower options if are looking to include it in your home or office. Geothermal Energy A geothermal energy plant uses heat from the Earth's interior in order to produce electricity. The process involves hot water and steam which naturally occur a few kilometers below Earth's surface. It is a renewable and sustainable energy source that generates electricity all day long, 365 days a year. Geothermal power can reduce our dependence on fossil fuels. It is also one of the most environmentally friendly methods of energy generation. The most well-known type of geothermal power plant is a flash-steam power station. This uses water at temperatures of approximately 182deg C (360deg F) to power turbines and generate electricity. The steam can also be used to heat buildings, or other industrial processes. Iceland for instance relies on the geothermal power to melt snow, heat its sidewalks, streets and parking spaces in the frigid Arctic Winter. Another geothermal energy source is a hot dry rock (HDR) power plant, which taps underground reservoirs of hot dry rocks that have been heated by either natural or human-made activities. HDR plants are easier to build and operate because they require less infrastructure. The National Renewable Energy Laboratory estimates that there is enough HDR resources in the United States to meet all of our current needs for electricity. The steam generated by geothermal power plants can be used to produce electricity by using a steam turbine generator, or it can be combined with a gas-fired generator to increase efficiency. The resultant mixture can be converted into natural gas, which is then burned in a traditional boiler to produce electricity. Geothermal energy is not just clean and reliable but also has the lowest carbon footprint of all renewable energy sources. Binary-cycle plants, which utilize an engine to convert steam into electricity, produce little-to-no nitrous oxide, methane, or sulphur dioxide. However, despite its advantages, geothermal energy isn't without its difficulties. The drilling required to construct geothermal power plants could trigger earthquakes and may pollute groundwater. Injection of high-pressure water streams into geothermal reservoirs can cause subsidence. This is a gradual sinking that can damage roads, structures pipelines, and other structures. Biogas Biogas is a renewable gaseous energy source that can be used to generate green energy. It is made from manure, agricultural wastes plants wastewater food wastes, municipal garbage and other organic wastes. Biogas can be used to generate electricity, heat and combined power and heat and can also be transformed into transport fuels using the Fischer-Tropsch process. Biogas can also be used to create renewable hydrogen that is used in fuel cells. Fuel cells are expected to play an important role in the future energy systems in the world. The most common method of valorising biogas is to generate electricity by using the power of a combined heat and (CHP) plant. The heat generated by the CHP plant is used to fuel the process of fermentation of organic wastes, while the electricity is fed back into the grid. It can be further compressed into natural gas and incorporated into existing natural gas distribution systems. Biogas can be utilized to replace imported mined gas in commercial and residential buildings, ground transportation and other areas. Biogas is a renewable energy source that can also help reduce greenhouse gas emissions. The CCAC is working to develop instruments for measuring, reporting and confirming (MRV) of the clean cooking practices in households and communities in countries with low to middle incomes, to help the 67 countries that have included clean cooking goals in their Nationally Determined Contributions (NDCs). Biogas can be used as an alternative to conventional natural gas for cooling and heating and to replace fossil fuels in electricity generation, carbon dioxide emissions will be reduced. Biogas can be used in the production of liquid transport fuels that can be an alternative that is sustainable to oil, coal, and other fossil fuels. Capturing and recovering methane from food and animal manure waste prevents the release of greenhouse gases into the atmosphere, and also preventing nitrogen runoff that could otherwise end up contaminating water resources. Plessis-Gassot is a non-hazardous waste disposal located in Claye-Souilly (France) for instance it captures and converts biogas into a renewable source of energy for households that are connected to the system. Additionally, small-scale biogas plants can be constructed in cities to allow for the collection and use of local organic waste which will reduce greenhouse gases associated with the transportation and treatment of these materials. Hydroelectric Power Hydropower is a renewable source of energy that is based on the kinetic energy of water flowing. It is the biggest and cheapest renewable power source in the world. It does not produce direct greenhouse gases but it does have significant environmental impact. It is a flexible form of green energy that can easily be adjusted to meet the changing demand and supply. It has a lifespan of more than a hundred years and can be upgraded for better efficiency and performance. greenpower mobility scooter of hydropower plants that are traditional use dams to harness the power of falling water. The energy generated by the water is converted into electricity through a series of turbines, which 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, operating costs are low. Furthermore, these plants can act as backups for other intermittent renewable power sources like solar and wind. Hydroelectric plants can be divided into two types: storage and run of river. Storage plants are characterized by large impoundments that store more than a season's worth of water. Run-of-river facilities have a small impoundment and use water from free-flowing rivers or streams. Hydropower facilities are typically located in or near concentrations of population, and in areas where there is a high demand for electricity. The environmental impact of hydropower is dependent on the size and location of a dam and the amount of water that is displaced as well as the wildlife and habitat affected by inundation and decomposition. These impacts can be minimized and mitigated by the use of Low Impact Hydroelectricity (LIHI) standards for the construction and operation hydropower projects. The standards provide measures to protect the river's flow and water quality passage for fish and protection, aquatic ecosystems, watershed protection, threatened and endangered species, recreation, as well as cultural resources. In addition to generating renewable energy, some hydropower plants act as the world's largest “batteries.” These are known as storage facilities that are pumped and operate by pumping water uphill from a lower pool to a higher reservoir. If there is greenpower mobility scooter for electricity, the water in the lower reservoir is released to power generators, while the water in the higher reservoir is pumped back downhill through a turbine to create more electricity.
