What Is Green Power? Green power is electricity that's produced from renewable sources like geothermal, solar, wind and biomass, as well as other forms of biomass and hydroelectricity that is low-impact. It's available to customers in deregulated markets who want to support cleaner energy sources by adding an additional cost to their utility bills. Many renewable energies are less damaging to the environment than drilling for coal or oil. They also can help us reduce our greenhouse gas emissions. Solar Energy Solar energy is a well-known green power source. Solar energy is considered to be as a renewable resource since it will never run out. It is a clean and efficient energy source, which helps reduce air pollution and greenhouse gas emissions resulting from fossil fuels, such as oil, coal natural gas, and coal. This energy source is a great alternative to nuclear power that requires the mining, extraction and storage of radioactive waste. The sun's radiation can be used to generate electricity in a variety of ways that include photovoltaic (PV) panels as well as concentrated solar-thermal power (CSP), and solar thermal collectors. Solar power can be directly channeled into businesses and homes, or it can be sent to grids that distribute electricity to other customers. Some consumers even 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 produce zero emissions of pollutants or air unlike fossil fuels which create 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 that cannot connect to the electrical grid is not feasible or even possible. Solar power can be utilized in smaller buildings. 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. Solar-powered homes also have the benefit of needing minimal maintenance. Another type of solar power is hydropower, which makes use of the natural flow of water in rivers, streams and dams to produce electricity. Hydropower, just like biomass and wind is a renewable resource as it can be replenished. If you're seeking to add hydropower to your home or business, check out EPA's list of third-party certified options. Geothermal Energy A geothermal energy plant uses heat from the Earth's interior in order to produce electricity. The process involves steam and hot water that naturally occur a few kilometers below the surface of the Earth. It is renewable and a sustainable energy source that produces electricity 24 hours a days throughout the year. Geothermal power could reduce our dependence on fossil fuels. It is also one of the greenest forms of energy production. The most common type of geothermal power plant is a flash-steam power 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 example, utilizes geothermal energy to melt snow and heat its streets, sidewalks and parking areas during the frigid Arctic winter. A hot dry rock power plant is an additional geothermal source of energy. It taps underground reservoirs composed of dry, hot rock that has been heated by either 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 is 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 produce electricity through a steam-turbine generator, or be combined with a gas-fired turbine to increase efficiency. The mixture can be converted 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, produce minimal or no methane, nitrous oxide or sulfur dioxide. Geothermal energy has its own difficulties, despite its benefits. Drilling required to build geothermal power stations could cause earthquakes and pollute groundwater. Furthermore, the dumping of high-pressure streams into geothermal reservoirs could cause subsidence, a slow sinking of the soil that could damage pipelines roads, buildings, and pipelines. Biogas Biogas is a renewable gaseous energy source that generates green power. It can be made from manure, agricultural wastes plants and sewage municipal garbage, food wastes, and other organic wastes. Biogas can be converted into transport fuels, electricity, heat, combined heat and energy, or electricity by using the Fischer-Tropsch method. Biogas can also be used to make renewable hydrogen which 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 to make biogas more valuable is by generating electricity in a combined heat and power (CHP) plant. electric scooter green from the CHP process is used to aid in the fermentation process of organic waste and the electricity generated is then fed into the grid. Alternatively, it can be converted into natural gas, and then incorporated into existing distribution networks for natural gas. Biogas can be used to replace imported mined gas in commercial and residential constructions, ground transportation and other areas. Biogas is renewable energy source that can also reduce greenhouse emissions of greenhouse gases. The CCAC provides tools for measuring reporting and confirming (MRV) the cleanliness of cooking in households of low- to middle-income countries. This will help the 67 countries who have included clean cooking targets in their Nationally Determined Contributions. Utilizing biogas as an alternative to conventional natural gas for cooling and heating and to replace fossil fuels in electricity generation, carbon dioxide emissions will be reduced. Biogas can also be used to produce liquid transport fuels that can be an alternative to oil, coal, and other fossil fuels. By capturing and recovering methane, we can prevent the release of greenhouse gases into the atmosphere and the runoff of nitrogen which could otherwise pollute our 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 supply of energy for households connected to the system. Additionally small-scale biogas plants could be installed in cities to allow for the collection and use of organic waste that is generated locally and avoiding the greenhouse gases that are associated with the transportation and treatment of these materials. Hydroelectric Power Hydropower makes use of the energy kinetics of water to generate electricity. It is the most powerful and cheapest renewable power source in the world. It doesn't emit direct greenhouse gases but it does have significant environmental impact. It is a highly flexible form of green power that is easily adjusted to meet the changing needs of demand and supply. It has a service life of over a hundred years and is able to be upgraded to improve efficiency and performance. The majority of hydropower plants that are traditional use dams to harness the energy of falling water. A series of turbines converts kinetic energy from the water into electricity at a rate that is proportional to its velocity. This electricity is then transmitted to the electric grid for use. Hydroelectric power plants require a significant investment in reservoirs and pipes. However the operating costs are minimal. These plants can also be used as backups for other intermittent renewable energy sources like wind and solar. There are two types of hydroelectric power plants which are run-of-river and storage. Storage plants are distinguished by large impoundments that store more than a season's supply of water, whereas run-of-river facilities have a small impoundment and utilize water from free-flowing streams or rivers. Hydropower facilities are typically located near concentrations of population, and in areas where there is a huge demand for electricity. The environmental impact of hydropower largely is dependent on the size and location of the dam as well as the amount of water displaced as well as the habitat and wildlife 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 a hydropower project. The standards include measures to protect river flows as well as water quality passage for fish and protection, watershed protection, threatened and endangered species, recreation and cultural resources. In addition, to generate renewable energy, some hydropower plants act as the world's biggest “batteries.” These are called pumped storage facilities and work by pumping water uphill from a lower pool to a higher reservoir. If electricity is required, the water from the lower reservoir can be used to power generators. The water from the reservoir above can then be pumped downhill via a turbine in order to create more electricity.
