Our power needs can be supplied by a number of sources. Each source of power come with its own set of advantages and disadvantages. For instance, fossil fuel may be an easy source of power and generate more than enough power we need, but it can be a major source of pollution. In addition, fossil fuel is a non-renewable resource; sooner or later, the world's supply of fossil fuel will disappear. Because of the disadvantages of using fossil fuel as a source of power and energy, solar energy is being considered by many as a possible major source of power. There is no question that solar energy can provide energy; however, the disadvantages of using solar energy have outweighed the advantages.
Converting Solar Energy into Electricity is Still Inefficient
The sun is the biggest source of solar energy. In fact, the energy coming from the sun and hitting us on Earth is several thousands times more than the power we use each year. Basically, our annual power consumption is way less than the energy that the sun provides us. From an idealistic point of view, the sun appears to be the best source of power.
However, one of the disadvantages of using solar energy as a source of power lies in the solar cells. The solar cells we currently use to convert solar energy into usable electricity are still not that efficient. This makes it difficult for us to take full advantage of all the energy we are getting from the sun. In addition, there is the issue of converting solar power. In order to use power from solar energy, it must be converted from direct current to alternating current. During this process of conversion, more energy is lost because of inefficiency. There is hope, however, that in time, more efficient solar cells and conversion process will be developed, and solar energy as a main source of power will become even cheaper and more viable.
Solar Energy Is Expensive
Solar power is free. After all, the sun is right there every day. We don't have to mine for solar energy nor do we have to transport solar energy back and forth and so on. However, there are costs involved in setting up solar power facilities. In terms of maintenance costs of these facilities, they are relatively low. The initial cost of putting up a solar facility is what's expensive. Typically, the start-up cost is large because solar panels are expensive. So a power grid with solar energy turns up to be more expensive than electricity from fossil fuel. Right now, solar facilities are still cost prohibitive to be put up in major cities and towns since fossil fuel comes out as the most economical option. Remote areas and island communities, however, can benefit from solar facilities since these places often do not have electricity yet. In addition, the price of solar power continues to steadily go down each year. In the case of solar energy, we will be able to fully take advantage of it when technology advances.
