pollution. Today new kinds of energy sources are being put into use but not enough to save our planet. In order for this to happen we need to convert to a lot of more alternative energy. A few of these types of energy are: Solar panels, wind turbines and nuclear energy, which all do not release toxic gases. However these energy sources also have pros and cons in multiple ways and aspects, two of them being socially and economically which makes the choice hard on which energy source to invest most in to
Energy can be defined as the ability to do work, which is accomplished by moving things. Renewable sources of energy are acquired from various natural sources. The main renewable sources are sunlight, wind, tides and geothermal. Sources of nonrenewable energy can be attributed to natural sources that are not regenerated once the source is depleted. Sources include fossils fuels such as coal and petroleum products e.g. natural gas and diesels. Pros of renewable energy sources: 1.Stable energy prices-
Nuclear Power Support or Fear The global energy demand is increasing as years go by as there is a rapid growth of population in deed of power. Due to the high demand for energy, many people are opting to replace other forms of energy with nuclear power because of its safety, reliability, and sustainability. In addition, it is one of the cleanest carbon free sources of energy available in the world today. Nuclear power is the use of continuous nuclear fission to produce electricity and heat. However
Solar electricity uses Photovoltaic (PV) modules to convert sunlight in to useable, storable, effective energy source. Photovoltaic is also known as the energy collector. The in which PV collector its energy is known as the photovoltaic effect. Alexander Edmund Becquerel describe the effect as the way PV cells create electricity through the energy residing in photons of light particular Sunlight. As the sun rays hit the PV module, the solar panel absorb some photons and the photons’ energy is transferred
formation of matter is because of energy and one of the examples of energy is the renewable energy. Renewable energy is energy that sources from natural resources that is constantly renewed on a human timescale and cannot be exhausted. Renewable energy is classified into five components which are hydro, wind, biomass, solar and geothermal energy (refer to Figure 1 in Appendix 1). The first type of renewable energy is the hydro energy. Hydro energy is a form of energy that is generated from the water
Nature’s Home Organisation also recommended wind energy as a replacement for coal. Wind energy, similar to solar energy, is renewable, causes no pollution and cannot be over-consumed. (Maehlium, 2015) This means the duration of the usage wind energy is very long. However, the wind is an irregular source of energy as there isn’t wind blowing at one certain area 24/7, but then again the price of wind energy have decreased over 80% since 1980 and they keep decreasing. (Maehlium, 2015) This means although
sustainable energy is indeed of primary importance. As the demand of electricity begins to outstrip supply the need for a reliable abundant alternative energy source is becoming more and more pressing especially in the few years to come. I am going to talking about why big business in South Africa be forced to go solar. Solar power is produced by collecting sunlight and converting it to electricity. This could be done using solar panels which are slat panels made up of many individual solar cells this
global warming situation as well as the constant fluctuations in the stock market. The introduction of nuclear energy on a larger scale could be the answer to the globe’s electricity needs. This could reduce the use of fossil fuels as well as generate a sizeable amount of electricity. This report looks at different methods of generating electricity and takes an in-depth look at nuclear energy, the advantages and disadvantages, as well as the sustainability thereof. 2. Other sources that generate
Should we pursue alternate energy sources? I feel that we should pursue alternate energy sources. It would stop pollution and global warming from happening so sudden, as we have it currently in our generation. Using renewable energy means that we will never run out of the energy we need. 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
Energy crisis, greenhouse effect, fossil fuel emissions, lack of natural resources, rising oil prices…just a few of the phrases you may have heard thrown around within the last few years. And, inevitably, you will have talked about, heard about or read about the need for the way we live with regard to our consumption of fossil fuels and the sources we use to fulfil our energy needs on earth to change, and to change drastically. The majority of the world’s current energy supply is obtained from
