Environment-friendly and renewable energy sources is an important topic to many. There are many renewable energy sources available such as the wind and solar power.
While the wind and solar power provide electricity, solar power is the one of many believe to be most effective out of the two. Solar power is the easiest source of energy that is found on Earth; it has always been around for us to use.
People are interesting on solar energy and whether or not it is our future. Many positive aspects outweigh some of the negative, and I think that solar energy has a possibility to be useful in the future. On day time my house is powered by solar energy. Euro Solar has installed a complete set of solar arrays to match my energy need. This actually helped me reduce my energy bills.
1. What Is Solar Energy and How Does It Work?
As the name suggests, solar energy is an energy source that comes from the sun. The fact that we have the ability to convert energy from the sun into electricity was an amazing breakthrough. We do not have to rely on fossil fuels as much because of this.
Solar power works as panels absorb sun radiation and turn it into electricity. In order to absorb the sun’s energy, panels need to be installed on the roofs of buildings. These panels called Photovoltaic (PV) panels are specially made to absorb the sun rays.
If you are wondering how PV panels use sun rays to make electricity, it is a simple process. After absorbing sun radiation, the electrons of the silicon cells in the panels use energy to make electricity.
2. The Pros and Cons of Solar Power
Like all energy sources, there are positive and negative aspects of solar power that we have to consider. While solar power has more positive than negative features, it is important to note the important aspects before we decide whether or not it is the future of energy consumption.
The main positive aspects of solar energy are:
- Constant amounts of energy
- Reduce electricity costs
- Technology is continuously improving
Solar power is renewable since it regenerates back into the earth. Because of this, solar energy itself is environmentally friendly compared to other energy sources like coal and nuclear power.
Unlike fossil fuels, solar power does not have the ability to run out. As long as there is a sun, you can make use of it. Another interesting aspect of solar power is that it can help you save money on your electric bill since you are using less power from your local power plant.
The technology for solar power is always improving, so the negative aspects of the energy source are dwindling, but there is still improvements that need to made.
Although there are only a few negative aspects of solar power, it is still important to mention them. The cons of solar power are:
- Expensive to install
- Space for panels
There is an obvious limitation to solar power since the sun is not always out. While solar power researchers and companies try to find ways to make solar power less limited in this way, night time and bad weather will affect solar power.
Another problem is that it costs a lot of money to install PV panels. To get solar energy, you have to hire companies that do this service, and the amount you pay varies with each company. Also, panels need a large space to be installed.
3. How Much Energy Does Solar Power Produce Worldwide?
The primary challenge to solar power is trying to convince people to use it. Many people worry about the efficiency of solar power, and the cost of installing solar panels. But solar power has shown some promise.
It is believed that the world has accumulative 117,003 megawatts in solar power usage. Many countries in the world are slowly moving towards using solar power. In fact, a 2010 study showed that Germany produces the most solar power in the world.
4. Is Solar Power Our Future?
It is hard to say with certainty whether or not solar power is going to be the main energy source in the future. However, if the technology improves enough to make installation cheaper, then yes it will eventually become the main energy source.
To conclude, Solar power is an important renewable energy source. It is starting to show that we do not have to rely on fossil fuels and other non-environmental friendly sources.
While I do not know what the future holds for alternative energy sources, I think solar power is going to become huge.
