Solar Energy Pros and Cons
Energy is defined in physics as the capacity to make things move; it is widely used in today people’s residences, a variety of industries and technology fields. Most of the energy we use now comes from fossil fuels coal, oil and natural gas, which are being consumed more rapidly than they are being replaced. That means eventually we will use up these fuels. That is why we as a society need to broaden our research to develop new forms of energy resources are for this happens. There are kinds of energy that can be replenished in short periods of time called renewable energy, these come from sources that are frequently being recycled and are consistently less polluting than energy that is produced from fossil fuels. There are five main kinds of renewable energy: biomass, hydropower, geothermal, wind and solar. Solar energy is provide by the sun in the forms of sunlight and heat, has been utilized the least even though it is probably the most accessible. However, solar energy holds a number of benefits for societies and it has already proven to have positive effects on residential homes and industrial applications. For many years, solar energy has been the economic choice for use in many industries where power is required at remote locations without government subsidy, as the vast majority of systems used require little electrical power. Solar energy is frequently used to power transportation signals. For example, offshore navigation buoys, lighthouses, and at an increasing rate traffic warning signals are using solar power due to its power saving efficiency. Solar power’s greatest benefit here is that it is highly reliable and requires little maintenance so it is ideal to use in places that are hard to access. Primarily, as I mentioned above, solar power is particularly useful in remote areas where it is lack of regular electricity supply. For instance, at Singleton, New South Wales, Australia, there are 2.75 hectare solar farm whose size is approximately
