For a long time now, there has been many research about the danger that fossil fuels have on our environment and health. Some of those dangers are the pollution of air and water, and global warming. For too long we have been relying on those dangerous fuels, so now it is time to shift to alternative and renewable energy sources.
The issues regarding fossil fuels and its effect on the changing climate has been stated by Svante Arrhenius, a Swedish scientist way back in 1896. Lately, this issue has become a hot topic especially when the general population starts to shift towards a healthier environment. A number of alternative energy sources are also rising.
Today, let’s talk about the alternative for renewable energy sources that will make our Earth healthier in the future!
1. Solar Power
Because our solar system revolves around the sun, the energy emitted by the sun has now become one of the most famous alternative or renewable energy. However, the cost for the installation of these renewable energy sources is really high, and you need to take care of the solar cell periodically because they are prone to deteriorate over time.
2. Hydroelectric Energy
In the early days of mankind, we already harnessed hydroelectric energy. However, as the usage of fossil fuels rose, we began to move away from this means of energy production. Despite all that, hydroelectric still powers around 7% of energy production in the U.S. alone. Not to mention, hydroelectric energy also contributes in irrigation technique and flood control.
3. Wind Energy
Another form of energy production that is getting more popular is wind energy, another alternative energy source that is renewable and produces no waste. In the U.S, this method of energy generation could produce enough energy to power 20 million houses a year. However, the fact that this energy production needs a massive wind turbine that could be dangerous for some wildlife and restrict views in many areas are a problem that is yet to be addressed.
4. Tidal Energy
The fact that our planet is covered by sea, it is only natural that we use the power of the sea and turn it into some form of energy, and that is where tidal energy comes from. The application of tidal energy is pretty much the same with wind energy, just without the wind turbine. Many sees tidal energy as the future of energy production, because it is estimated that this method of energy production could fill at least 20% of the electricity demand in the United Kingdom.
Biofuel is the hot new thing when it comes to energy production. In the U.S alone, biofuel is responsible for 7% of transport fuel consumption in 2012. However, there is a concern when it comes to biofuel. While biofuel does not contribute to increased emissions, they still require dedicated machinery to actually extract the biofuel. Those machines might actually contribute to the increased emissions.
6. Hydrogen Gas
As an alternative energy producing method, hydrogen gas will only emit water vapor and warm air. However, hydrogen gas is mostly derived from massive usage of natural gas and fossil fuels. That is why, many argue that the benefit of hydrogen gas is counteracted by the emissions created to extract them.
The idea of geothermal power is to extract the energy stored in the ground. Lately, this method of energy production is growing steadily, with a growth of 5% in 2015. The World Bank estimates that Geothermal Power could meet the energy demands of at least around 40 countries.
At the moment, nuclear power is the most famous and potential form of alternative energy because of how low emission and efficient it is. At the same time, it also boosts the economy by creating many jobs during the plant creation and operation. However, people are still wary of nuclear power plants due to the incident of Chernobyl and Fukushima.
With the advancement of technology, there might come a day where we could finally be free of fossil fuels and use renewable energy alternative instead. By doing so, we might also be helping the Earth to recover back and rewind the global warming.
