Our fossil fuels are running out. We cannot deny that. Scientists have predicted that oil will run out in 40 years, natural gas in 60 years adn coal in 220 years. People have suggested "renewable energy", but will this new source of energy to satisfy our crave for power and energy? Renewable energy has been a greatly controversial topic that has been brought up in recent years due to the oil crisis. Renewable energy is not new to us. It has been here for many years, since the oil crisis was predicted. Although renewable energy seems like our only hope, it is quite undeveloped, and we still have much to master.

There are many pros and cons to renewable energy. Here i am going to discuss them.
One of the major pros is that it produces little or none greenhouse gases. Burning fossil fuels usually produce greenhouse gases wich trap heat withing the earth, making it hotter every year. Renewable energy sources usually do not produce greenhouse gases, as they rely on other ways to spin the turbines to generate energy.

The second pro of renewable energy is of course, it is renewable. It does not require the burning of fossil fuels to make energy, so it can still produce power even after our oil supply runs out. It does not drain the limited amount of fossil fuels we already have, instead they tap into limitless sources of energy.

However, renewable energy also has a lot of cons.
Firstly, these new sources of energy are wuite expensive and not really worth it. They cost a lot more that the conventional burning of fossil fuels and it does not produce much energy compared to buring fossil fuels. That is why many countries prefer using fossil fuels to produce cheap energy. They also cost much money to research and perfect, and governments are usually reluctant in leaving so much money aside for research.

Secondly, renewable energy also sometimes causes changes to the environment. For example, hydroelectric energy makes use of water in order to produce power. It affects the ecology and causes downstream problems. Decay of vegetation on the riverbed can also cause a buildup of methane which contributes to the greenhouse effects. Dams may also cause an alteration of the natural river flow and affect wildlife in the area as well. Water which is colder and which is lacking in oxygen tends to be released into the water this kills the fish, sudden release of water like this may also result in flooding. Flooding can also be caused by the dam operators, who release the water too fast, causing the river to flood downstream.

Geothermal energy makes use of the steam from the Earth's ground in order to generate power. These plants can bring up toxic chemicals and heat from the earth when it tries to obtain the steam, releasing it into the area around it, killing wildlife around it. Drilling such geothermal reservoirs can also cost a lot.


With ocean energy, during construction and putting in place of pipes may damage the ecosystem.

Some renewable sources of energy are also erratic and does nto produce a constant supply of electricity.
For example, solar power is not a constant source of energyas it is also limited to the daytime as well as non-cloudy days.
. Solar radiation is also controlled by geography.

In wind energy, the wind turbines are huge and they have to be placed where little people are living. These places might not be suitable, as the wind might be too weak, or there is no wind at all. Wind turbines only produce electricity when there is strong wind, which cannot be gaurenteed.



Although renewable energy has many cons, it is currently our only opiton in creating energy without fossil fuels, with the exception of nuclear power. Until we discover a new way of producing power, we have no choice but to stick with the current methods of producing renewable energy.
