Solar energy

Energy plays an important part in social and economic develop. As the oil price sharply increases, it stimulates the step of researching the renewable energy field. The advantages of using renewable energy reduce the dependence on fossil fuel resources and carbon emission to the atmosphere. The total incoming solar radiation is about 3.8 million EJ per year and it can satisfy the entire energy demand if utilise correctly [2]. The use of solar energy is usually identified in two contexts: passive solar energy systems, which use natural processed without mechanical equipment and no additional energy and active solar energy systems, which utilise solar energy with the assistance of mechanical equipment [3]. Solar thermal collectors, photovoltaics,…

One of the main concerns surrounding solar energy is the endangerment of birds that pass over these solar farms. These birds, including threatened and endangered species, often mistake the reflective solar facilities for a body of water, a phenomenon known as the “lake effect.” Honing in on these water bodies, many birds have been fatally singed or crippled due to these desert solar power plants (Upton, 2014). These plants produce a solar flux that is the sum of the focused rays of light…

One of the alternative plan is replacing coal-fired energy to solar energy in the industrial factories, in order to reduce the carbon dioxide (CO2), sulfur dioxide (SO2) and the nitrogen oxides (NOx). As most of scientists mentioned, the CO2 is one of the major greenhouse gas that causes the global warming; SO2 and NOx have link to several respiratory illnesses. In order to decrease the temperature globally and the cases of respiratory illnesses, the reduction of CO2, SO2 and NOx are the goals…

People have been finding, and using sources of energy since the beginning of mankind. Whether it is fire to cook, use streams and rivers to ride a canoe, to help grind corn, or coal to power trains across the world, humans have always relied on the valuable riches that the earth produces to survive However, most of the energy that is currently being used is nonrenewable, which means that it will not replenish as quickly as it is being consumed. An example of a nonrenewable resource currently…

Solar power, simply put, is energy that comes from sunlight. Solar energy is used to power things such as streetlights, homes, or even smaller things such as calculators. Many people have switched to solar energy to power their home’s electrical appliances, as it is commonly believed that solar energy is better for the planet. While solar energy does provide us with energy without burning fossil fuels, there are also other effects on the planet. Before understanding how solar energy impacts the…

always will be, the Earth 's largest energy reservoir-it powers every living system, from plant photosynthesis to every node of the food web. Humans, like all other organisms, depend on sunlight" (6-10). Why not use the sun even more? Taking the sun 's energy to create a harmless, clean source of power is better than most of our current means of power. Solar power is already implemented in everyday things. For example, ever notice new street lights or new crosswalk traffic signs? Notice the…

Today, 80% of the energy people use come from fossil fuels and about 1% comes from solar energy. This can be seen as not being a very practical use of energy sources since nonrenewable resources are limited. Renewable sources can be replenished and have a much smaller chance of running out than nonrenewable sources. Solar energy is one of the least used energy sources that people have access to in the world; it is also one mother Earth is relying on to save the nonrenewable fuels, such as coal.…

Solar Energy, the Superior Alternative Energy Fossil fuels are bad for our environment, and in an economy that is struggling, there is no point in pouring billions of dollars a year into an energy source that is killing our other resources. This kind of spending and reckless destruction of our environment will eventually have to stop. The question is, when burning burning fossil fuels ultimately ceases, where will we turn? There are many forms of alternative energy that are accessible to us…
