What Is Green Power? Green power is electricity that comes from renewable sources like geothermal, solar and wind biomass, energy and hydroelectricity with a low impact. Customers in deregulated markets 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 environment than coal or oil mining. They can also reduce greenhouse gas emissions. Solar Energy Solar energy is among the most popular green sources of power. Solar energy is a renewable source because it is never depleted. It is an efficient, clean and secure energy source that can reduce greenhouse gas emissions as well as air pollution from conventional fossil fuels like natural gas, coal and oil. This energy is a good alternative to nuclear power, which requires mining, extraction and storage of radioactive waste. Solar thermal collectors, photovoltaic panels and concentrated solar thermal energy (CSP) are all methods to harness the power of the sun. Solar power can be distributed directly to businesses and homes or to grids that distribute electricity to other. Some consumers even can sell 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 no air emissions or pollutants, unlike fossil fuels that generate carbon dioxide and other harmful gases when they burn. Solar energy can also be used to power other types of devices, including spacecrafts, boats, satellites and other vessels in areas where accessing the electricity grid is either impossible or not practical. On smaller scales, solar can be used to power buildings. Many homeowners use PV solar panels on their roofs to produce electricity, and passive solar home design lets these homes let in sunlight during the day to provide warmth and then retain it in the evening. Solar-powered homes also benefit from the requirement for little maintenance. Another form of solar power is hydropower, which uses the natural flow of the water in streams, rivers and dams to generate electricity. Like biomass and wind hydropower, hydropower is a renewable resource because it can be replenished. If you're seeking to add hydropower to your home or business take a look at the EPA's list of third party certified options. Geothermal Energy A geothermal energy plant harnesses heat from the Earth's interior in order to produce electricity. The process makes use of steam and hot water that naturally occur a few kilometers below the surface of the earth. It is a renewable and sustainable energy source that can generate electricity 24 hours a day throughout the year. Geothermal power is a great way to reduce our dependency on fossil fuels. It is also one of the greenest sources of energy generation. The most common type of geothermal power plant is a flash steam power station. This makes use of water at temperatures of approximately 182deg C (360deg F) to power turbines and generate electricity. Steam can be utilized to heat industrial processes and buildings. Iceland, for example, uses geothermal energy to melt snow and heat its streets, sidewalks, and parking lots in the frigid Arctic winter. Another source of geothermal energy is the hot dry rock (HDR) power plant that taps underground reservoirs of hot dry rock that are heated by either natural or human-made activities. HDR plants are simpler to construct and operate since they require less infrastructure. According to the National Renewable Energy Laboratory, there is enough HDR resources available in the United States for all of our current electrical requirements. The steam generated by geothermal power plants can be used to create electricity through a steam-turbine generator, or be coupled with a gas-fired turbine to increase efficiency. The mixture can be transformed into natural gas, and then burned in a boiler to generate electricity. Geothermal energy is not just reliable and clean, but it also has the lowest carbon footprint of all renewable energy sources. Binary-cycle plants, which use an engine to convert steam into electricity, generate little-to-no nitrous oxide, methane or sulfur dioxide. Geothermal energy has its own problems, despite the advantages. Exploring for geothermal power stations can cause earthquakes and also pollute the groundwater. Injection of high-pressure streams in geothermal reservoirs can cause subsidence. This is a gradual sinking process that can cause damage to roads, structures, and pipelines. green power folding mobility scooter is a gaseous renewable energy source that can be used to produce green energy. It can be made from manure, agricultural wastes plants, sewage, municipal garbage, food wastes, and other organic wastes. Biogas can be used to create electricity, heat and combined heat and power, or it can 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 predicted to play an important role in the future energy systems of the world. The most popular method to make biogas more valuable is by generating electricity in the combined heat-and-power (CHP) plant. The heat produced by the CHP process is used to assist in the fermentation process of organic waste and the electricity generated is then fed into the grid. It can be further compressed into natural gases 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. In addition to generating renewable energy, biogas can help reduce carbon dioxide emissions and pollution from conventional cooking. The CCAC is working to provide instruments for measuring, reporting and verification (MRV) of the clean cooking practices in communities and households in low- to middle-income countries in order to assist the 67 countries that have incorporated clean cooking as a goal in their Nationally Determined Contributions (NDCs). Using biogas to replace fossil fuels for electricity generation as well as a substitute for traditional natural gas for heating and cooling will reduce carbon dioxide emissions as well as other air pollutant emissions. Biogas can also be used to create liquid transport fuels that can be an alternative to oil, coal and other fossil fuels. Capturing and recovering methane from animal manure and food waste helps to prevent 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 in Claye-Souilly (France) for example, captures and converts biogas into a renewable source of energy for homes who are connected to the system. Additionally small-scale biogas facilities can be constructed in cities to allow for the collection and use of organic waste from local sources and avoiding the greenhouse gases that are that are generated by the transport and treatment of these materials. Hydroelectric Power Hydropower harnesses the energy generated by the kinetic energy of water to generate electricity. It is the most popular and cost-effective source of renewable energy in the world. It releases no greenhouse gases, but it does require significant environmental impacts. It is a flexible form of green energy that is able to be adjusted to meet changing demand and supply. It has a service life of more than 100 years and can be upgraded to improve efficiency and performance. Most traditional hydropower plants harness the energy of water falling through dams. The energy generated by the water is converted to electricity by the use of turbines which spin at a speed proportional to the speed of the water. The electricity is then transferred to the electric grid to be used. Hydroelectric power plants require a large investment in pipes and reservoirs. However, operating costs are low. Furthermore, these plants can be used as backups to other intermittent renewable power sources like solar and wind. Hydroelectric power plants can be classified into two types that are storage and run-of-river. Storage plants are characterized by large impoundments, which can store more than one season's worth of water. Run-of-river plants use streams and rivers that flow freely. Hydropower plants are often situated near or in areas with high density of population in areas where demand for electricity is high. The environmental impact of hydropower is dependent on the size and location of the project, the amount of water displaced, as well as the habitats and wildlife that are affected by decomposition and flooding. These effects can be minimized and reduced through the use of Low Impact Hydroelectricity Standards (LIHI) for the construction and operation of a hydropower project. The standards cover measures for the flow of rivers, water quality protection, fish passage, protection of aquatic ecosystems endangered and threatened species, recreation and cultural resources. In addition, to generate renewable energy Hydropower plants also function as the world's largest “batteries.” They are called pumped storage facilities and work by pumping water uphill from a lower pool to a larger reservoir. When 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 via a turbine in order to create more electricity.
