By harnessing energy from the sun, dependence on more environmentally harmful sources as oil and coal can be decreased.This is a great alternative to these nonrenewable resources. Solar energy reduces the destruction of pristine forests.These forest make carbon dioxide to clean up the toxins in the air. Without all of these forest the climate changes rapidly. Solar power keeps this from happening. A positive effect of solar power is that it saves you money.
III. Disadvantages of Solar Power Development The initial cost for purchasing a solar system is fairly high. Although the UK government has introduced some schemes for encouraging the adoption of renewable energy sources, for example the the Feed-in Tariff, you still have to cover the upfront costs. This includes paying for solar panels, inverter, batteries, wiring and for the installation. Nevertheless, solar technologies are constantly developing, so it is safe to assume that prices will go down in the future.
We preserve our planet for future generations by looking at the role science is playing to cut down carbon-based energy to move to renewable low-carbon energy to meet our constantly increasing demands of electricity consumption. Green electricity benefits us to produce electricity from sources which would not harm or pollute our environment. For sure, few electricity bases may also have influences but they are much greener than the others. The most suitable energy sources are the renewable energy sources, as they will never expire or run out. (Figueiredo, João Neiva De, 2014) Nuclear energy is number one in the production of electricity.
According to the Energy Information Administration (solar vs coal 2), 15 years ago, the electricity industry made a huge shift towards renewable sources of energy because of its cheap availability and increasing popularity. The author also compared the coal and the solar energy of at this time as a new electricity generation. Both solar and coal produce energy, but solar energy is more beneficial because of its efficiency, construction cost, and is environmentally safe and healthy. Everyone needs energy for various purposes. The first thing to consider while choosing the energy for us is its efficiency.
• Environmentally Friendly – This means that Solar Panels do not cause any pollution, which therefore does not affect the world negatively. • Reduces Electricity Costs – It reduces electricity costs because you can harvest your own electricity to use. • Shared Solar – Because Solar Energy can be run “off the grid” energy produced can be shared. • Low Maintenance – As solar panels are one piece it because a lot less risky that smaller pieces will fall apart or break which lowers cost. • Remote Areas – Solar Panels can help to provide electricity to areas which may be far from another electrical source.
“The fuel in the earth will be exhausted in a thousand or more years, and its mineral wealth, but man will find substitutes for these in the winds, the waves, the sun 's heat, and so forth”- claimed scientist John Burroughs stating that the fuel in the earth will last longer with wind power. Wind is air in motion which is caused by the heating of Earth’s surface by the sun. Wind power doesn’t release pollution into the air or water and is a renewable source which we can never ran out of unlike fossil fuels. It can also produce electricity, and can help control in fossil fuel costs as well. Wind power helps keep a longer lasting fuel, a clean and safe environment, and lastly reduce our dependence on fossil fuels.
"Solar" is the Latin word for "sun" - and is a powerful source of energy. In fact, sunlight shining on the Earth in one hour could meet global energy demand for an entire year! We can use solar energy in two ways: as a heat source, and a source of energy. People have used the sun as a heat source for thousands of years. Families in ancient Greece built their houses to get the most sunlight during the cold winter months.
Concentrator solar power concentrates light energy from the sun on a smaller surface to boil a liquid. The steam then spins turbines to generate electricity. This is might be cheaper than using photovoltaics because you don’t need to store the energy for overnight. The thermal storage allows for electricity to be generated for up to 24 hours. There are many types of technologies to do this, for example parabolic trough, compact linear Fresnel reflectors, Stirling solar dish and solar power tower.
Almost none of the fuel sources that we could use provide Co2 or other pollutants. Economic values could also come from renewable energy. Most of the Energy projects are located away from big cities. These benefits could bring local service as well as tourism. Although the pros are very big there are some cons.
PROS Its extremely cheap: Geothermal energy generally involves low running costs since it saves 80% costs over fossil fuels and no fuel is used to generate the power. Since, no fuel is requiring so costs for purchasing, transporting and cleaning up plants is quite low. CONS The main disadvantage of geothermal energy, is that it requires dry ground and freshwater to proceed into the extraction, in some countries freshwater cannot be wasted, since it’s a vital source of energy BIOMASS ENERGY Biomass is any material that comes from plants or microorganisms that recently died. Plants create energy through photosynthesis, this energy stays stored inside the plant even after its death. Trees, branches, scraps of bark and even derivatives from plants like paper, are common sources of biomass energy, also garbage, crops like corn, soy and sugar can be used to produce biomass.
