What Is Green Power? Green power is electricity produced by renewable resources such as solar, wind, geothermal and some forms of biomass and hydroelectricity with low impact. Customers who are in markets that are not regulated can add a small premium to their utility bills to help support renewable energy sources that are cleaner. Renewable energy sources are generally less environmentally harmful than drilling for oil or mining coal. They also can aid in reducing greenhouse gas emissions. Solar Energy Solar energy is a popular green power source. Solar is considered a renewable resource because it will never run out. It is a clean, efficient and safe energy source that helps reduce greenhouse gas emissions and pollution of the air from fossil fuels such as coal, natural gas and oil. This energy is a great alternative to nuclear power that requires the mining extraction, storage and storage of radioactive waste. The sun's radiation can be used to generate electricity in a variety ways such as photovoltaic (PV) panels as well as concentrated solar-thermal power (CSP), and solar thermal collectors. Solar power can be distributed directly to businesses and homes or to grids which distribute power to others. Certain consumers can sell their surplus energy back to the utility company, which could help keep electricity bills low and even offset rising utility costs. All forms of solar energy generate no air emissions or pollutants unlike fossil fuels, which produce carbon dioxide and other harmful gases during their combustion. Solar energy can also be used to power other types of devices, like satellites, boats and spacecrafts, where accessing the electrical grid is not feasible or even possible. Solar power can be used in smaller structures. Many homeowners use PV solar panels on their roofs in order to generate electricity and passive solar home design permits these homes to let in sunlight in the daytime for warmth, and then store the warmth at night. Solar-powered homes also benefit from the fact that they require little maintenance. Hydropower is a type of solar energy that uses the natural flow of streams, rivers, and dams. Similar to biomass and wind, hydropower is considered renewable since it can be replenished. If you're looking to add hydropower to your home or business take a look at the EPA's list for third-party certified options. Geothermal Energy A geothermal plant uses heat from the Earth to produce electricity. The process involves steam and hot water that naturally occur a few kilometers below surface of the Earth. It is a renewable and sustainable energy source that produces electricity 24 hours a days all year round. Geothermal energy can reduce our dependence on fossil fuels, and is one of the most eco-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 generate electricity and power turbines. Steam can be utilized to heat industrial processes or buildings. Iceland for instance, utilizes geothermal energy to melt snow and heat its streets, sidewalks, and parking lots during the frigid Arctic winter. A hot dry rock power plant is a different geothermal source of energy. It taps underground reservoirs made up of dry, hot rock that is heated by either man-made or natural processes. HDR plants are easier to build and operate because they require less infrastructure. The National Renewable Energy Laboratory estimates that there are enough HDR resources in the United States to meet all of our current electricity needs. The steam from geothermal power plants can be used to create electricity by using 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 produce electricity. Geothermal energy is not only safe and reliable, but also has the lowest carbon footprint among all renewable energy sources. Binary-cycle plants that use an engine to convert steam into electricity generate little or no nitrous dioxide methane, sulphur, or methane oxide. Geothermal energy is not without its challenges, despite the benefits. Drilling required to build geothermal power stations can cause earthquakes and pollute groundwater. In addition, the injection of high-pressure streams into geothermal reservoirs may lead to subsidence, which is a gradual sinking soil that could damage pipelines, roads, and buildings. Biogas Biogas is a gaseous renewable energy source that can be utilized to produce green power. It can be produced from agricultural wastes, manure, plants wastewater, food wastes, municipal garbage and other organic wastes. Biogas can be used to transportation fuels, electricity, heat combined with energy, or electricity using the Fischer-Tropsch method. Biogas can also be used to produce renewable hydrogen that is used in fuel cells. Fuel cells are expected to play a significant role in the future energy systems of the world. The most popular method of valorising biogas is to generate electricity through the use of a combined heat and power (CHP) plant. The heat produced by the CHP plant is utilized to fuel the 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 the existing natural gas distribution networks. Biogas can also be used as a replacement for natural gas imported from mines in commercial, ground transportation and residential constructions. Biogas is a renewable energy source that can also help reduce greenhouse emissions of greenhouse gases. The CCAC is working to provide tools to measure, report and verification (MRV) of healthy cooking within communities and households in low-to-middle income countries in order to assist the nations that have included clean cooking targets in their Nationally Determined Contributions (NDCs). Utilizing biogas as an alternative to conventional natural gas for cooling and heating and to replace fossil fuels used in electricity generation, carbon dioxide emissions will be reduced. Biogas can also be used to create liquid transport fuels that can be a sustainable alternative to coal, oil, and other fossil fuels. Recovering methane from food and animal manure waste helps to prevent the release of greenhouse gases into the atmosphere, as well as preventing nitrogen runoff that could otherwise pollute water resources. The Plessis Gassot waste landfill, which is non-hazardous in Claye-Souilly, France, for instance, captures biogas and turns it into a sustainable source of energy for homes connected to the system. In addition, small-scale biogas plants can be installed in cities to facilitate the collection and utilization of organic waste from local sources which will reduce greenhouse gases caused by transport and treatment of these materials. Hydroelectric Power Hydropower harnesses the energy kinetics of water to generate electricity. It is the most affluent and cost-effective renewable energy source in the world. It doesn't produce direct greenhouse gases however it has significant environmental impacts. It is a highly flexible form of green power that can be easily adjusted to meet changing supply and demand. It has a service life of more than a hundred years and is able to be upgraded for improved efficiency and performance. Most traditional hydropower plants use dams to harness the power of falling water. A series of turbines converts the kinetic energy from the water into electricity at a rate that is proportional to its velocity. The electricity is then transferred to the grid of electricity for use. Although constructing a hydroelectric power plant requires an enormous investment in reservoirs, dams and pipes, operating costs are relatively low. Furthermore, these plants can act as backups to other intermittent renewable power sources like wind and solar. Hydroelectric plants can be classified into two types: storage and run of river. Storage plants are characterized by large impoundments, which can store more than one season's worth of water. mobility power scooters -of-river facilities draw water from rivers and streams that are free-flowing. green power folding mobility scooter are typically located in or near concentrations of population, where there is a high demand for electricity. The environmental impact of hydropower depends on the size and location of a dam and the amount of water that is displaced and the habitat and wildlife affected by decomposition and inundation. These impacts can be reduced and diminished by utilizing Low Impact Hydroelectricity Standards (LIHI) for the construction and operation of a hydropower projects. The standards contain measures to protect river flows and water quality passage for fish and protection, watershed protection, threatened and endangered species, recreation and cultural resources. Some hydropower plants are also the world's biggest “batteries” because they generate renewable energy by pumping water from a lower reservoir uphill to a bigger reservoir. When electricity is needed the water from the lower reservoir can be used to power generators. The water from the upper reservoir can then be pumped downwards through a turbine to create more electricity.
