solar cell electricity, they both must be defined. Green building, a term also known as green construction or sustainable building refers to a structure and the use of processes that are environmentally responsible and also efficient when it comes to resources throughout the life cycle of the building essays on renewable energy from siting to the essays on renewable energy, construction, essays on renewable energy, the operation, its maintenance, renovations that are made and demolition. Increased Attention on Nuclear Power: As previously mentioned,… Works Cited: Adamson, Greg. With the United States recently moving in the right direction, it will be better. If anything, the billowing of black smoke from oil fields, or the sight of millions of liters of water trapped behind a dam, or even the sheer massiveness of a nuclear or geothermal power plant are more unpleasant, if not scary to the eye. New Century Senior Physics. This is not a problem of itself, but combined with the fact that the negative externalities of development, from climate change to pollution to garbage, are often poorly priced into the cost of goods.

We use cookies to give you the best experience possible. Fuel Cell: Fuel cells have been known to science for years and have become the subject of intense research since World War II. A fuel cell generates electricity by producing a chemical reaction. It consists of two electrodes cathode and anodewhich is also where the reaction occurs. Hydrogen is the basic fuel cell, but all fuel cells also require oxygen, and both are essays on renewable energy from external reservoirs. Most of the hydrogen and oxygen used, combine to form a harmless byproduct, essays on renewable energy, namely water.
Therefore, essays on renewable energy, fuel cells generate electricity with very little pollution. It is the purpose of the fuel cells to produce an electrical current that can be directed outside the cell to do work, such as powering light bulbs or an electric motor. Biomass Energy: This is one of the oldest sources of energy known to man. Biomass energy is energy from organic matter. The organic matter contains stored sunlight in the form essays on renewable energy chemical energy. Biomass fuel, which can be a liquid, solid, or gas, comes from plants, residues from agriculture or forestry, and the organic component of municipal and industrial wastes.
Even the fumes from the landfills can be used, essays on renewable energy. When the fuel is burned, the energy is released. The use of this energy has potential to greatly reduce greenhouse gas emissions. The waste generates about the same amount of carbon dioxide as fossil fuels but as the plants grow for biomass purposescarbon dioxide will be removed from the atmosphere. This is the major source of energy in the developing world. Wind Energy: Surface air currents that are warmed by solar rays create wind, which is an indirect source of energy. Wind farms consist of many wind turbines, that when moved by the wind, produce electricity for utilities. The turbines sit high atop towers to take advantage of the stronger less turbulent winds.
Wind turbines can stand alone, or be connected to a utility power grid, or combined with a PV system. The energy is used for generating electricity, charging batteries, pumping water, or grinding grain. There are no air pollutants or greenhouse gasses emitted. Wind energy is also a competitive resource. Hi there, would you like to get such an essay? How about receiving a customized one? Check it out goo. Essays Database Energy Renewable energy Essay.

In order to competently compare photosynthesis and semiconductor-based solar cell's production of electricity i. solar cell electricity, they both must be defined. These processes are similar because they both require sun light, transform that sun light and both processes are environmentally friendly. Photosynthesis and semiconductor —based solar cell production of electricity have many differences. How solar cells work. htm United States. Luckily, there are many means alternative energy sources to conserve the earth's limited natural resources. As the world continues to grow and have need for energy, applied science will discover more alternate energy sources to be used in the future.
Works Cited Energy Story. Wind Energy, 15 April www. html Green Nature. Some technologies are used to produce heat from solar energy. Other technologies use solar energy to produce electricity. Thermal Solar Energy Hot Water Heaters: The easiest way to exploit solar radiation is as thermal energy. One way to harness this solar energy is to heat water. ct solar radiation onto a single point above the mirror. Next, millions of people will be give These efforts aim to reduce the consumption of energy derived from traditional fossil fuels. Renewable energy is any natural sources that can replenish itself or renew itself over a period if time. There are four major sources of renewable resources, solar power utilizes the idea of trapping or harness energy from the light of the sun in order to power electrical devices or provide heating or cooling to your local home or building.
Geothermal energy is a product that uses the earth's heat to produce electrical energy to your needs. The new source of renewable energy is solar thermal. Solar thermal is using heat from the sun to generate electric energy. The other name of solar thermal energy is concentrated solar power CSP. The method of electric generation is by uses mirror to focus sunlight to a medium. Then the medium transfer heat to boiler. Solar Energy ~Some history, types, and facts~ In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these.
One of the few disadvantages it has is that it is difficult to generate the quantities of electricity that are as those produced by traditional fuel generators. This would mean that we would have to reduce the amount of energy we use or built more energy which can be very expensive. Another drawback of renewable energy sources is the reliability of supply. Renewable energy often relies on the weather of its source of power. Hydro generators need rain to fill dams to supply flowing water. Wind turbines need wind to turn the blades, solar collectors need clear skies and sunshine to collect heat and make electricity.
When these sources are unavailable so is the capacity to make energy from them. This can be unpredictable and inconsistent. Furthermore, the wildlife habitats are destroyed because of the wind farms. Many people think that it is a very cruel behaviour to the wildlife. They have lives like us, so how would we feel if some kind of new powerful creatures came and killed thousands of us, in a flash of a second? Even though there are negative points to renewable energy, there are lots more positive points that suggest renewable energy is only part of the best way to prevent global warming.
However, humankind has no choice but to take renewable energy very seriously. It is gaining more respect daily and there are numerous reasons as to why this is the case. Fossil fuels are damaging the planet and this can be our way of doing something about that. The most important part is that renewable energy is commitment free and sustainable. Greenhouse gases and other emission will reach all time lows, possibly zero. This deduction is important to slow the rate of climate change and global warming. Stopping climate change and gas emissions in its tracks would also lead to more health benefits. There are dozens of deadly diseases and carriers that spawn from the irregular climate patterns. Also, climate change could affect physiological needs by lessening safe drinking water, food supply and shelter.
The United States has a reputation of being an innovator, a leader for many countries. It has a history of being scared of change; people are too comfortable with life as it is, but it could be better. With the United States recently moving in the right direction, it will be better.
