The energy transition promises a more wealthy and peaceful world, free of oil, pollution, and scarcity. This official premise, however, reveals to be a myth: by abandoning fossil fuels, we are setting ourselves up for a new reliance on rare metals. Also, by shifting to renewable energy, we are preventing future generations from benefiting from its abundance. Finally, technological progress needs constant input of non-renewable resources, so this dream can never become reality.
In conclusion, green energy is not only viable but necessary for our survival as well. The problem is that it is not being done properly or completely enough. We need more research and development into sustainable energy sources before we run out of options. In the meantime, we must keep using fossil fuels because they are reliable and there is no alternative yet that can replace them.
Here are some examples of how green energy has failed us so far: solar panels require silicon, which comes from mining, so they are not truly renewable; wind turbines need large amounts of metal for their construction, which gets recycled at best; and even hydroelectric plants need lots of concrete to build their reservoirs, which is bad for the environment.
So yes, green energy is good idea whose time has come but it needs improvement before we can rely on it entirely.
A step toward a greener future and long-term development. Depleting natural resources such as coal, petroleum, and water may not be available for a long time unless we save and utilise them efficiently for the future while also identifying other, renewable energy sources such as solar and wind. Developing countries that rely on fossil fuels will be affected first by the rising cost of these fuels and later by climate change.
A step away from despair. We need new ways to generate electricity that do not depend on fossil fuels or nuclear power. However, this process is difficult and requires significant investment. Therefore, it is important to start now if we want our children and grandchildren to enjoy an environment without pollution.
A step toward a healthier future. Green energy has many advantages over traditional energy sources such as coal and oil which are harmful to the environment and human health. By switching to green energy, we can reduce air pollution, greenhouse gases, and dependence on foreign countries for energy supplies.
A step toward a more secure future. The global economy depends on affordable and reliable energy supplies. If the existing energy sources begin to run out, there will be a major disruption in the economy and society. This is why it is important to develop alternative energy sources that are safe and sustainable.
A step toward a better world. Human activity has had an impact on the environment that is damaging its ability to support life.
Energy produced by the combustion of fossil fuels (coal, oil, and natural gas) is a major contributor to climate change. We must immediately transition away from fossil fuels and modernize the technology that powers our homes, industries, and offices, grows our food, and drives our transportation. This will help us reduce our dependence on fossil fuels and protect our environment.
Dirty energy includes traditional sources of energy like wood and coal as well as oil and natural gas derived from fossil fuels. These sources are used to produce power because they are easy to find and use. However, they also cause pollution when burned. The term "dirty energy" has been used by many environmental organizations to describe energy sources that pollute air quality, deplete the earth's resources, or both.
Fossil fuels consist of large amounts of carbon trapped in rock formations over millions of years. They include oil, natural gas, and coal. Oil and natural gas are the main components of gasoline and other chemicals. Coal is the main component of electricity generators.
The burning of fossil fuels contributes to greenhouse gases entering the atmosphere, such as carbon dioxide. This affects the global temperature and can lead to more frequent drought and floodings. It can also cause the ice caps at the poles to melt, leading to ocean level rises and making low-lying areas such as islands and coastal cities vulnerable to flooding.
More research has resulted in the development of more efficient equipment, making renewables more cheap. Wind and solar energy are technologies, not fuels, therefore as science advances, they become more affordable. Fossil fuel technology may improve fuel economy, making them less expensive, but it isn't the sole cause. Climate change and natural disasters can also impact costs.
The cost of solar electricity has decreased by 80% since 2010. The price of wind power has dropped by 50% in the same time period. These prices will only continue to drop as more companies enter the market.
Renewable energy sources such as solar and wind are becoming increasingly popular due to their low or zero carbon emissions. The climate change argument has helped drive down the cost of solar and wind energy. There are also certain countries with government support such as Germany who have encouraged this shift towards renewable energy.
Another reason why renewable energy is so inexpensive is because of mass production. Solar panels and wind turbines are both manufactured in large quantities which lowers the per unit cost. Science has also played a role here - solar cells have improved significantly over time. When solar cells were first developed in the 1950s, they could only convert up to 15% of light energy into electrical energy. Now they average about 30%. As science progresses, we will be able to create better solar cells that cost less and less.
Finally, renewable energy sources are free!
