What are the Advantages and Disadvantages of Using Green Energy Sources?
Today, we are now aware of the effects of global warming. Fortunately, it’s not too late and we can still change which is why many are pushing for green energy sources.
The advantage of using green energy sources is that it is clean so it does not emit anything harmful into the air which has an impact on the environment. It is also renewable which means we will never run out of it unlike oil which is expected to dry up in a decade or so.
Although green energy facilities are expensive to build, it requires less maintenance so you don’t have to shell out a lot of money to operate it.
It can also bring economic benefits to certain areas even boost tourism.
While these sound good, there are some who say that there are advantages to using such technology.

- 2,000-watt pure sine Xantrex inverter with two outlets and a USB port allows you to plug in small devices
- Battery not included, a minimum of one 12 Volt deep cycle battery is necessary to use this kit
While green energy sources can produce electricity, how much it can generate is not consistent. This is because we have no control of the weather so if a certain area relies on solar energy and there is a weather disturbance, it will not be able to convert sunlight into electricity.
Building these facilities also requires a lot of land so we may have to cut on farmland which is what many are concerned about if more wind turbines are to be put up.
Another disadvantage is the fact that some of the green energy sources cannot be installed in certain areas of the planet. For instance, wave energy can only be utilized if the waves coming from the ocean reach at least 16 feet. The use geothermal energy can only be done in geologically unstable parts of the planet.
But if you look at such arguments, places that cannot use one form of green energy source can be substituted for another. If wind turbines need more space, they can be installed near the coast instead of putting these on land. A study shows that you can generate more electricity while these are in the ocean.
While the weather is something we cannot control, it is not everyday that there is a weather disturbance so this too shall pass. If solar energy is being used and the sun is covered, the emergency generators will be activated and use up the energy that was stored.
The point is that there are ways around the arguments put by certain individuals which discourage the use of green energy sources. In fact, research is ongoing to try and harness other means to generate the power we need.
A very good example of this is called ocean thermal energy. Power is generated by harnessing the different temperatures in the water. It is currently being used on a small scale both in Japan and Hawaii.
In the US, only 7% of green energy sources are used nationally. This was much higher 11 years ago and if we don’t have to worry about the cost of oil or even reduce our dependency on it, we have to invest more in this clean energy.
We can get it from green energy sources such as biomass, biodiesel, geothermal, solar, water and the wind. These are things we have all around us and all it takes is for someone to harness it instead of relying on traditional non-renewable means to produce energy.
