Many countries today are trying to find green solutions to the problems that started in the pre-industrial times. We can see that some of these green solutions are at work such as the use of hydropower and geothermal energy. However, the factors that affect the overall capacity of these solutions to function may not consistent. For example, solar energy may not reach the desired energy output due to sunlight inconsistency brought by weather conditions. Huge risk and high cost are another factors that hold back some nations to fully harness renewable sources of energy. Why?
Coal is the widely used fossil fuel in power generation. It is known that burning these materials emit large amounts of carbon dioxide and is now threatening the world by posing harmful effects such as ocean acidification, sea level elevation, global warming and more powerful typhoons or hurricanes. The reason why coal is widely used despite its adverse effects is that it is relatively cheaper than the renewable sources of energy stated above. In the meantime, transportation is also one major cause of massive greenhouse gasses emission in the atmosphere. Electric cars that are featured in movies are now on the road but compared to those motorists who are using oil for transportation, these electric cars are insignificant, for now of course.
It is certain that countries will try to find more sustainable ways on how to maximize the use of renewable sources of energy considering the risk and cost of implementing them. For now, the world is moving with a pace mostly driven by the power of fossil fuels. The question is, can renewable energy hold back the threats imposed by climate change? Not really. The use of renewable energy may only lessen its effects. Climate change is part of the earth’s process that is somehow intensified by harmful activities made by humans. In sum, green solutions may not hold back the threats but lessen its effects on humans and the environment.
