Apart from the cost of the equipment, installation requires skilled labour and is not cheap (this is true for any mass energy generating equipment). The resource, however, is completely free. After initial costs, maintenance is fairly cheap, as the solar panels contain no moving parts and are less likely to break down. Sun tracking equipment may require additional maintenance, but much less so than traditional energy generation
No need to kill animals and cut trees. Excavation of earth to search petroleum is also avoided. Only a little noise pollution us created during the wind turbine rotation. Although it is required relatively large amount of area to construct many of the wind turbines, it can also be a perfect harmony to the environment and all the living things can remain to stay here without the need of sacrifice. It will never stop when there is a wind resource and seems to be a long lasting energy resource.
First generation biofuel is made from food crops or feed stocks that can also be consumed as human food by extracting the oils through fermentation. Crops like wheat, sugarcane, corn, sugar beet and sorghum are some of the main sources of producing biofuel. Since their availability and extraction through conventional means they are termed as conventional biofuels. Most common first generation biofuel includes:- (1) Biodiesel. Extracted from vegetable oils, animal fats, seeds from plants like Soybeans, Canola, and Sunflower are few of the examples.
Carbon from the atmosphere is absorbed into plants during photosynthesis and when the plant decays or is burnt that carbon goes back into the atmosphere. Because it is a cycle, the next crop of plants absorb that carbon over again, so this process does not contribute much to the release of carbon dioxide into the atmosphere. 3.2 Cons of Biomass Energy 3.2.1 Requires Space Big areas are required for all the different processes that is required in harnessing energy from biomass. The areas that are needed for storing can be particular large and may lead to deforestation. 3.2.2 Emissions The principal concerns about emissions and the impact of combustion systems on air quality are in relation to carbon dioxide and carbon monoxide (〖CO〗_2 and CO), small particulates (PM10 and PM2.5; particles smaller than 10 microns and 2.5 microns respectively), oxides of nitrogen (NOx) and sulfur dioxide (〖SO〗_2).
Pros & Cons of Solar Energy These types of benefits and negative aspects cover places for example solar power for your house, and also the commercial utilization of solar energy. Solar power Benefits: Solar power panels produce absolutely no air pollution, the only real air pollution created due to solar power panels may be the production of those gadgets within industrial facilities, transport from the products, as well as set up. The actual creation of one's through the utilization of fossil plus some alternative energy sources could be loud; however, solar power generates electrical power really silently. Among the excellent benefits associated with solar power may be the capability to control electrical power within remote control areas
Solar energy is the energy received by the earth from the sun that is converted into thermal or electrical energy (Tran et al., 2016). It is an important source of renewable energy and its technology are roughly branded as either solar energy or active solar provisional on how they capture and distribute solar energy or converted it into solar power. Although solar energy influence earth’s climate and weather, solar energy provide 0,5 percent of the world’s electricity, expect believes that sunlight has the potential to supply 5000 time as much energy as the world consumes (Tran et al., 2016). Broadly speaking, solar energy is a term used to describe a range of methods for obtaining energy from the sun. The large magnitude of solar energy available
The improper disposal of oil and garbage results in land, water, and air pollution. Renewable energy sources occur naturally and are inexhaustible. They do not originate from fossil or nuclear fuels which make them the ideal solution for the preservation. Only a small percentage of the energy used is supplied by renewable sources. Types of renewable energy sources include wind, wave, solar, tidal, and hydroelectric power.
Hydropower is a fueled by water, so it's a clean fuel source. Hydropower doesn't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Hydropower is a domestic source of energy, produced in the United States. Hydropower relies on the water cycle, which is driven by the sun, thus it's a renewable power source. Hydropower is generally available as needed; engineers can control the flow of water through the turbines to produce electricity on demand.
“Renewable energy resources that is naturally regenerated over a short time scale and derived directly from the sun, indirectly from the sun or from other natural movement and mechanisms of the environment. Renewable energy does not include energy resources derived from fossil fuels, waste product from fossil sources, or waste products from inorganic sources.” There are a few types of renewable energy sources. 1) Wind Energy 2) Biomass 3) Hydropower 4) Geothermal 5) Solar All electricity sources, renewable and nonrenewable, have advantages and deficiencies. Factors are includes: • Maintenance cost • Feasibility analysis. • Initial cost.
