Solar energy is more cost efficient and cleaner than the use of fossil fuels. Due to the limited supplies of fossil fuels and the polluting impacts on global climates and the air, a renewable energy future is absolute essential(Wright and Boorse). Much of the worlds required energy can be supplied directly by solar power. The biggest difference between solar energy and fossil fuel is that solar energy has not been stored in the form of chemical energy as it has been for fossil fuels. The three fundamental problems with solar energy are: collection, solar energy is widely scattered and so large areas must be covered for collection.
Organically grown foods mean that the crops are grown without the use of pesticides or any chemicals. Non organic foods however, lack a lot of its flavor, and health benefits are lower than Organic foods, because there are some other chemical products added in to it. I do not buy Organic fruits or vegetables all the time because it cost more than a Non Organic food. However, whenever I buy non organic fruits or vegetables, I make sure that I rinse them properly before eating. Doing so will remove the pesticides and the chemical that was use to make them grow.
There is lots of renewable energy such as solar energy, wind energy, geothermal energy and hydroelectric energy. There are many benefits of alternative energy. Most of alternative energy is friendly to environment and people. They will not consume fossil fuel and cause almost no air pollution, so they will not harmful environment. Harnessing of renewable energy is keeping the world from running out of energy, delays and decrease greenhouse effects and global warming because using renewable energy can
For example, when I am both at home and at my workplace, we usually use power saving and energy efficient light-bulbs which do not consume such high amounts of energy compared to other sources. Another example would be regarding my vehicle (however, this can be viewed from multiple perspectives). Instead of using fuel to power up my vehicle, I would use an electrical vehicle which would not pollute the environment, but it would have to consume electricity to be charged. Anyway, research is still undergoing in this field. I can do conservation of energy when it comes to heat energy by only powering up the heat system when needed, and not wasting heat energy.
(Mieg &Töpfer, 2013)Urban sprawl has the benefit because of that low density area is more environmental friendly, the large amount vegetations filled in the low-dense area can absorb the carbon dioxide made by the activities of human beings, which causes less amounts of air and water has been polluted by the pollutants. It has been observed that the more green areas are preserved in low-dense areas and there are more open spaces for people to entertain. (Xu,2014) But at the meanwhile,in the reality,developing low-dense area need to replace farmland or open space. However, the approach of urban sprawl will causing the lost of open space and natural habitats because of land
Wind turbines are clean, effective and nonpolluting; however, one cannot predict the speed or direction exactly. The heavier populated areas require more energy. Not enough wind and the turbine will not turn. Wind turbines are noisy, threatens wild life, and is an eye sore along with costly for the initial funding. Solar energy is a non-pollutant, cost effective, maintenance free, life span of up to 40 years; however the upfront cost is enormous, and not everyone can afford the cost to put the stylish panels on their roof tops.
You can build your own electricity generator by using solar panels. When you generate your own solar power, you don't have to deal with any bills from the utility company. Besides, a big benefit to use solar technology is that it is a renewable and clean type of energy. Solar power cannot create large amounts of CO2 that fossil fuel can. In other words, I believe
The mechanical power is converted into electricity to power homes and businesses. Wind plants produce electricity that emits zero pollutants. The environmental concern from the wind power plants is minimal; the problems that arise are the noise created from the rotator blades and the killing of birds by flying into the blades. With some technological advances, that issue was drastically reduced. Another major challenge is that the wind does not blow all the time, therefore, the turbines do not spin and no power is created during these
Answer = As far as the water is concerned based solely on carbon, I do not feel that it has a huge impact on the water, but when it is used as a source for energy, it is not as clean burning as one is to believe. Though however, sometimes lead and other heavy metals can be drain into our water from abandoned mines.
The maintenance of fuel cells is simple since there are few moving parts in the system. Fuel cells provide high quality DC power. Use a variety of fuels, renewable energy and clean fossil fuels. The power densities are high values. Cogeneration Capability.
