What Is Green Power? Green power is electricity produced from renewable sources such as solar, wind and geothermal energy, biomass and hydroelectricity that has a low environmental impact. Customers in deregulated markets are able to add a small fee to utility bills to support green energy sources. Renewable energy sources are typically less harmful to the earth than coal mining or oil drilling mining. They also can help us reduce greenhouse emissions of greenhouse gases. Solar Energy Solar energy is a well-known green energy source. Solar is considered as a renewable resource since it will never run out. It is an efficient, clean and secure energy source that can reduce greenhouse gas emissions as well as air pollution caused by conventional fossil fuels such as natural gas, coal, and oil. This energy source is a great alternative for nuclear power which requires the mining extraction, storage and transport of radioactive waste. The sun's energy can be utilized to generate electricity in a variety ways that include photovoltaic (PV) panels, concentrated solar-thermal power (CSP) and solar thermal collectors. Solar energy can be directly channeled into homes and businesses or it could be sent to grids that distribute electricity to other customers. Some consumers can sell excess energy to the utility company. This can reduce electricity bills and offset rising utility costs. All forms of solar energy produce zero air emissions or pollutants unlike fossil fuels, which produce carbon dioxide and other harmful gases when they burn. Solar energy can be used to power satellites boats, spacecrafts and other devices in areas in areas where accessing the grid is either difficult or impossible. Solar power can be used in smaller buildings. Many homeowners use PV cell panels on their roofs in order to generate electricity and passive solar home design allows these houses to let in sunlight in the daytime for warmth and then retain it in the evening. Solar-powered homes also benefit from the fact that they require very minimal maintenance. Hydropower is a kind of solar energy that uses the natural flow of streams, rivers, and dams. Hydropower, just like biomass and wind is a renewable resource because it can be replenished. Check out the EPA's list of third party certified hydropower options if are looking to include it in your office or home. Geothermal Energy A geothermal plant utilizes heat from the Earth to produce electricity. The process makes use of hot water and steam that naturally occurs a few kilometers below the surface of the Earth. It is an incredibly renewable and sustainable energy source that produces electricity all day long and 365 days of the year. Geothermal power is a great way to reduce our dependency on fossil fuels. It is also among the most eco-friendly forms of energy generation. green power mobility scooters uk of geothermal power plant is a flash steam power station. It uses water at temperatures of approximately 182deg C (360deg F) to generate electricity and power turbines. Steam can be used to heat industrial processes or buildings. Iceland, for instance, is dependent on geothermal power to melt snow and heat its sidewalks, streets and parking spaces in the frigid Arctic Winter. A hot dry rock power plant is another geothermal source of energy. It taps underground reservoirs composed of dry, hot rock heated by man-made or natural activities. HDR plants require significantly less infrastructure than geothermal power plants, which makes them less expensive and easier to construct and operate. According to the National Renewable Energy Laboratory, there are enough HDR resources available in the United States for all of our electrical needs currently. The steam generated by geothermal power plants can be used to create electricity through a steam-turbine generator, or it could be combined with a gas-fired turbine to improve efficiency. The resulting mixture can then be converted to natural gas, which is burned in a conventional boiler to produce electricity. Geothermal energy isn't just safe and reliable, but also has the smallest carbon footprint of all renewable energy sources. Binary-cycle plants that utilize an engine to convert steam into electricity create minimal or no nitrous oxide methane, sulphur, or methane oxide. However, despite its benefits, geothermal energy isn't without its challenges. The drilling required to establish geothermal power plants can trigger earthquakes and could cause groundwater pollution. Injection of high-pressure streams in geothermal reservoirs could cause subsidence. This is a gradual sinking that can damage roads, buildings pipelines and buildings. Biogas Biogas is a renewable gaseous energy source that can be used to produce green power. It can be produced from manure, agricultural wastes plants and sewage, food wastes, municipal garbage, and other organic wastes. Biogas can be used to create electricity, heat and heat and power or converted into transport fuels through the Fischer-Tropsch process. Biogas can also be used to create renewable hydrogen, which is then used in fuel cells. Fuel cells are predicted to play a major role in the future energy systems of the world. The most common method of valorisation of biogas is to generate electricity through 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 then fed back to the grid. It can also be converted into natural gas, and then incorporated into existing natural gas distribution networks. Biogas can be used as a substitute for natural gas imported from mines in commercial, ground transportation and residential constructions. In addition to generating renewable energy, biogas can also help reduce greenhouse gas emissions and pollutants from cooking conventionally. The CCAC is working to provide tools to measure, report and confirming (MRV) of clean cooking in households and communities in low- to middle-income countries, to help the 67 countries that have incorporated clean cooking targets in their Nationally Determined Contributions (NDCs). Biogas can be used as an alternative to traditional natural gas for cooling and heating and to substitute fossil fuels in electricity generation carbon dioxide emissions will be reduced. Biogas is also a viable substitute for coal, oil and other fossil fuels for production of liquid transportation fuels. By taking methane and reusing it to prevent the release of greenhouse gases into the air and the evaporation of nitrogen that could otherwise pollute our water sources. Plessis-Gassot, a non-hazardous landfill located in Claye-Souilly (France), for example it captures and converts biogas into a renewable source of energy for households that are connected to the system. Small-scale biogas facilities can also be set up in cities, allowing for the collection and utilization of organic waste locally. This will reduce greenhouse gas emissions associated with transportation and treatment. Hydroelectric Power Hydropower is a renewable energy source 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 emit direct greenhouse gases but will have significant environmental impacts. It is a flexible form of green energy that can easily be adjusted to meet changing demand and supply. Its service life spans over 100 years and can be upgraded to increase efficiency and performance. The majority of traditional hydropower plants harness the power of falling waters by using dams. A series of turbines converts energy of the water into electricity at a speed that is proportional to its velocity. This electricity is then sent to the grid to be used. Although constructing an hydroelectric power plant involves an enormous investment in dams, reservoirs and pipes, operating costs are low. These plants can also be used as backups for other intermittent renewable energy technologies such as solar and wind. Hydroelectric plants can be classified into two kinds which are storage and run-of-river. Storage plants are distinguished by huge impoundments that hold more than a season's worth of water, whereas run-of-river facilities are small in size and use water from free-flowing streams or rivers. Hydropower facilities are often situated near or in proximity to areas of people, in areas where there is a huge 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, and the wildlife habitats and habitats affected by inundation and decomposition. These impacts can be minimized and reduced through the use of Low Impact Hydroelectricity (LIHI) standards for the construction and operation hydropower projects. The standards contain measures to control water quality, river flows, protection passage of fish, protection of aquatic ecosystems endangered and threatened animals as well as recreation and cultural resources. Some hydropower plants are also the world's largest “batteries” because they generate renewable energy by pumping water from a lower pool uphill to a larger reservoir. If electricity is required, the water from the lower reservoir can be used to power generators. The water from the upper reservoir can then be pumped downwards by a turbine to create more electricity.
