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 It is available to consumers in markets that are not regulated and who wish to support cleaner energy sources by putting the cost of their utility bills Renewable energy sources are generally less harmful to the earth than oil drilling or coal mining They can also help us reduce our greenhouse emissions of greenhouse gases Solar Energy Solar energy is a favored green energy source Solar energy is a renewable source since it never runs out It is a safe and efficient energy source which reduces air pollution and greenhouse gas emissions from fossil fuels like oil coal and natural gas It is an excellent alternative to nuclear power which requires the mining and extraction of uranium and longterm storage of radioactive waste The suns radiation can be used to generate electricity in a variety ways that include photovoltaic PV panels concentrated solarthermal power CSP and solar thermal collectors Solar energy can be channeled directly into homes and businesses or it can be transferred to grids that distribute electricity to other customers Certain consumers 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 types of solar energy create no air emissions or pollutants unlike fossil fuels which generate carbon dioxide and other harmful gases when they burn Solar energy can be used to power satellites spacecraft boats and other devices in areas that are located in areas where access to the grid is difficult or impossible Solar power can be used in smaller structures Many homeowners put PV solar panels on their roofs to generate electricity and passive solar home design lets these homes let in sunlight during the day to provide warmth and then store it at night green power mobility scooters uk powered homes also benefit from the fact that they require very little maintenance Hydropower is a different kind of solar energy that makes use of the natural flow of rivers streams and dams Like biomass and wind hydropower it is renewable since it can be replenished If you are planning to incorporate hydropower into your home or business check out the EPAs list for thirdparty certified options Geothermal Energy A geothermal energy plant draws heat from the Earths interior to generate electricity The process makes use of hot water and steam that naturally occurs just a few kilometers below the surface of the Earth It is a remarkably sustainable and renewable energy source that generates electricity all day long all year round Geothermal power could reduce our dependency on fossil fuels It is also one of the most environmentally friendly forms of energy generation The most common geothermal power station is a flashsteam plant This makes use of water heated to 182deg C or 360deg F to power turbines and produce electricity The steam can also be used to heat buildings or other industrial processes Iceland for instance is dependent on geothermal power to melt snow and heat its streets sidewalks and parking spaces in the frigid Arctic Winter Another source of energy from geothermal sources is the hot dry rock HDR power plant which taps underground reservoirs of hot dry rocks that are heated by manmade or natural activities green power scooter reviews are less difficult to construct and operate as 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 electricity needs Steam from geothermal power stations can be utilized as a source of electricity by using a steam turbine generator or in conjunction with gasfired turbines to improve efficiency The resultant mixture can be converted to natural gas which is burned in a conventional 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 Binarycycle plants that use an engine to convert steam into electricity produce littletono nitrous oxide methane or sulphur dioxide However despite its benefits geothermal energy isnt without its problems Exploring for geothermal power stations can cause earthquakes and pollute the groundwater Additionally the injection of highpressure streams into geothermal reservoirs can lead to subsidence which is a gradual sinking of the terrain that can cause damage to pipelines roads pipelines and even buildings Biogas Biogas is a renewable gaseous energy source that can be used to produce green power It can be made from manure agricultural wastes plants wastewater municipal garbage food wastes and other organic wastes Biogas can be used to produce electricity heat and combined power and heat or converted into transport fuels through the FischerTropsch process Biogas is also a great resource for producing renewable hydrogen to be used in fuel cells which are likely to play a major role in the future of energy systems The most popular 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 utilized to fuel the fermentation of organic wastes In turn the electricity is fed back into the grid Biogas can also be compressed into natural gases and incorporated into existing natural gas distribution systems Biogas can be used to replace imported mined gas in residential and commercial buildings ground transportation and other areas Biogas is a renewable energy source that can also help reduce greenhouse emissions of greenhouse gases The CCAC is working to develop tools to measure report and confirming MRV of healthy cooking within communities and households in countries with low to middle incomes to assist the 67 countries that have incorporated clean cooking targets in their Nationally Determined Contributions NDCs Utilizing biogas to replace fossil fuels for electricity generation as well as a substitute for conventional natural gas in cooling and heating will reduce carbon dioxide emissions as well as other air pollutants Biogas is also a viable substitute for oil coal and other fossil fuels in the production of liquid transportation fuels By capturing and recovering methane by capturing and recovering methane we can stop the release of greenhouse gases into the atmosphere as well as the evaporation of nitrogen that could otherwise pollute our water resources The PlessisGassot landfill for nonhazardous waste in ClayeSouilly France for instance is a biogas capture facility that transforms it into a sustainable source of energy for households connected to the system Additionally smallscale biogas plants could be installed in cities to permit the collection and utilization of local organic waste and avoiding the greenhouse gases that are caused by transport 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 most soughtafter and least expensive renewable energy source in the world It does not emit greenhouse gases directly but it has significant environmental effects It is a very flexible form of green power that is able to be adjusted to meet the changing needs of demand and supply Its lifespan is more than a century and it is able to be upgraded to improve efficiency and performance The majority of hydropower plants harness the power of water falling through dams The kinetic energy of the water is converted to electricity by a series of turbines which spin at a speed proportional to the velocity of the water The electricity is then transferred to the electric grid for use While building an hydroelectric power plant involves huge investments in dams reservoirs and pipes operating costs are low These flexible plants can also be utilized as backups to other intermittent renewable energy technologies like wind and solar Hydroelectric plants can be classified into two types which are storage and runofriver Storage plants have large impoundments which can store more than a seasons worth of water Runofriver plants use the water of streams and rivers that are freeflowing Hydropower plants are usually located close to or in areas of high density and where the demand for electricity is high The environmental impact of hydropower depends on the size and location of the dam as well as the amount of water displaced and the wildlife and habitat affected by inundation and decomposition The effects of hydropower can be mitigated and reduced by using Low Impact Hydroelectricity Standards LIHI for the construction and operation of hydropower project The standards contain measures for water quality river flows protection passage of fish aquatic ecosystems protection endangered and threatened species recreation and cultural resources Some hydropower plants are also the worlds largest batteries because they produce renewable energy by pumping water from a lower reservoir uphill to a larger reservoir When electricity is required the water from the lower reservoir could be used to power generators The water from the upper reservoir can then be pumped downwards by a turbine to create more electricity
