What Is Green Power? Green power is electricity that's generated from renewable resources like geothermal, solar, wind and biomass, as well as other kinds of biomass and hydroelectricity that is low-impact. It's available to customers in markets that are not regulated and who wish to support cleaner energy sources by putting a small premium to their utility bills. Renewable energy sources are typically less harmful to the environment than coal mining or oil drilling mining. They also help reduce greenhouse gas emissions. Solar Energy Solar energy is a popular green energy source. Solar energy is a renewable source since it never runs out. It is an efficient, clean and safe energy source that reduces greenhouse gas emissions as well as air pollution from conventional fossil fuels such as natural gas, coal and oil. This energy source is also a viable alternative to nuclear power, which requires extraction and mining of uranium, as well as long-term storage of radioactive waste. The sun's energy can be utilized to create electricity in a variety of ways, including photovoltaic (PV) panels and concentrated solar-thermal power (CSP), and solar thermal collectors. Solar energy can be directly channeled into homes and businesses, or it can be delivered to grids that supply electricity to other customers. Some consumers even have the option of selling their surplus energy back to the utility company, which helps keep electricity bills low and even offset rising utility costs. All forms of solar energy produce zero emissions of pollutants or air unlike fossil fuels which produce carbon dioxide and other harmful gases during their combustion. Solar energy can be used to power satellites boats, spacecrafts and other devices in areas that are located in areas where access to the grid is either difficult or impossible. Solar power can be utilized in smaller structures. Many homeowners put PV solar panels on their roofs to produce electricity and passive solar home design lets these homes take in sun's rays during the day for warmth, and then store it in the evening. Solar-powered homes also benefit from the fact that they require very little maintenance. Hydropower is a different type of solar energy that utilizes the natural flow in streams, rivers dams, and streams. Like wind and biomass, hydropower is considered renewable because it can be replenished. If you're planning to incorporate hydropower into your home or business take a look at the EPA's list of third party certified options. Geothermal Energy A geothermal energy plant draws heat from the Earth's interior to produce electricity. The process makes use of steam and hot water that naturally occurs a few kilometers below Earth's surface. It is an environmentally sustainable and renewable energy source that can generate electricity all day all year round. Geothermal energy can reduce our dependence on fossil fuels, and is one of the most eco-friendly forms of energy generation. The most popular geothermal power station is the flash-steam plant. This makes use of water at temperatures of approximately 182deg C (360deg F) to generate electricity and power turbines. The steam can also be used to heat buildings, or other industrial processes. Iceland, for instance, relies on the geothermal power to melt snow and heat its streets, sidewalks and parking lots in the frigid Arctic Winter. A hot dry rock power plant is another geothermal source of energy. It taps underground reservoirs composed of hot, dry rock heated by man-made or natural activities. HDR plants require less infrastructure than geothermal power plants, making them more affordable and less costly to construct and operate. 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. green scooters from geothermal power plants can be used to produce electricity through a steam-turbine generator, or it can be combined with a gas-fired generator to improve efficiency. The mixture can be converted into natural gas and burned in a boiler to generate electricity. In addition to being safe and reliable, geothermal energy also has the smallest carbon footprint among all renewable energy sources. Binary-cycle plants that use an engine to convert steam into electricity produce very little or no nitrous dioxide methane, sulphur, or methane oxide. Geothermal energy comes with its own difficulties, despite its benefits. The drilling required to establish geothermal power plants can trigger earthquakes and may pollute groundwater. Additionally, the injection of high-pressure streams into geothermal reservoirs could cause subsidence, which is which is a gradual sinking of the terrain that can cause damage to pipelines roads, pipelines, and even buildings. Biogas Biogas is a natural gaseous energy source that can be used to generate green power. It can be made from manure, agricultural waste, plant material, municipal waste, sewage, food waste and other organic waste materials. Biogas can be used to produce electricity, heat and combined power and heat or transformed into transport fuels using the Fischer-Tropsch process. Biogas is also a valuable resource for generating renewable hydrogen for use in fuel cells that are expected to play an important role in the future of energy systems. The most common way to make biogas more valuable is by generating electricity in the combined heat-and-power (CHP) plant. The heat from the CHP process is used to aid in the fermentation of the organic waste, and the electricity is then fed into the grid. Biogas can also be converted into natural gas and incorporated into existing natural gas distribution systems. Biogas can also be used to substitute for imported natural gas in commercial, ground transportation and residential buildings. Biogas is an energy source that is renewable and can also reduce greenhouse emissions of greenhouse gases. The CCAC is attempting to provide tools to measure, report and verification (MRV) of healthy cooking in households and communities in low- to middle-income countries in order to assist the nations that have included clean cooking goals in their Nationally Determined Contributions (NDCs). Utilizing biogas to replace fossil fuels to generate electricity and as an alternative for traditional natural gas in cooling and heating will reduce carbon dioxide emissions and other air pollutants. Biogas is also a sustainable alternative to oil, coal and other fossil fuels for production of liquid transportation fuels. Capturing and recovering methane from food and animal manure waste stops the release of greenhouse gases into the atmosphere, while also preventing nitrogen runoff that would otherwise cause water pollution. Plessis-Gassot, a non-hazardous landfill located in Claye-Souilly (France) for example it captures and converts biogas into a sustainable source of energy for homes that are connected to the system. Additionally small-scale biogas facilities can be constructed in cities to facilitate the collection and utilization 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 flowing water. It is the largest and most affordable renewable source of power worldwide. It releases no direct greenhouse gases but has significant environmental impact. It is a flexible form of green power that can be easily adjusted to meet changing demand and supply. It has a service life of more than 100 years and is able to be upgraded to improve efficiency and performance. The majority of hydropower plants harness the energy of falling waters by using dams. The energy generated by the water is converted into electricity by a series of 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. Additionally, these plant are able to serve as backups for other intermittent renewable power sources like solar and wind. There are two main kinds of hydroelectric plants: storage and run-of-river. Storage plants have large impoundments, which can store more than one season's worth of water. Run-of-river facilities draw water from rivers and streams that flow freely. Hydropower plants are usually located near or in areas with high density and where the demand for electricity is high. The environmental impact of hydropower is dependent on the size and location of the dam as well as the amount of water displaced and the wildlife and habitat affected by decomposition and inundation. These impacts can be reduced and reduced through the use of Low Impact Hydroelectricity Standards (LIHI) for the construction and operation of the hydropower project. The standards cover measures for water quality, river flows, protection and fish passage, as well as aquatic ecosystems protection, threatened and endangered animals recreation and cultural resources. Some hydropower plants are also the world's largest “batteries” because they can 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, while the water in the upper reservoir is pumped back downhill through turbines to generate more electricity.
