Large hydropower and new renewable together are referred to as modern renewable. The 20th century marked the emergence of fossil fuels which

Causes of Air Pollution In the world nowadays‚ there are many new inventions have invented. They are including cars‚ motorcycles‚ electronic gadgets and the machines that use the burning of fossil fuel. Instead of the benefits of these new inventions‚ there are many disadvantages‚ too. There are two main reasons that cause air pollution. One of the main causes of air pollution is manufacturing. This source of pollution spews particulate matter and chemicals into the atmosphere. The particulate

technology that has been developed in China. Largely developed because of China’s low carbon footprint in comparison to other developing countries‚ the low carbon technology aims to offset the amount of emissions polluting the air by using renewable fossil fuels. (Xie 1594) China is a low carbon economy for two main reasons. First‚ the number of people that own a car is far lower than the national average of a country like the United States.

large deposits of natural gas‚ there will be less usage of fossil fuels. With the fossil fuels being used over a greater period of time‚ research can be done to discover cleaner alternative energy sources. While natural gas is still detrimental to the environment‚ it does cause less carbon dioxide emissions than fossil fuels‚ so this is a common argument for fracking. While this argument makes sense if you are comparing gas to fossil fuels‚ it still pollutes the environment more than energy sources

It is a form of energy derived from a natural source‚ such as the sun‚ wind‚ tides‚ or waves and are also known as “Renewable Energy” that do not use up natural resources or harm the environment. They are considered alternatives because they can be future replacements for the fossil fuels that now meet a considerable portion of our energy needs. What Energy Resources are we using now

problems. Pollution comes in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal‚ or oil. When fossil fuels are burned they give off a green house gas called CO2. Also mining coal and oil allows methane to escape. How does it escape? Methane is naturally in the ground. When coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well. Another major man-made

Climate Change‚ Capitalism‚ and Social Justice California used to be a paradise‚ lush green lawns freshly cut‚ creeks gurgling with water‚ and mountains covered in golden fields. What happened? The lawns are all shriveled up‚ dry rocks are left where there used to be water‚ and black blotches on hills are left behind from wildfires. Scientists state that this is a result of climate change‚ also known as global warming. When warm temperatures affect the weather patterns of the Earth‚ the effects are

Advantages and disadvantages of solar energy: The major benefit of solar is avoiding green house gases that fossil fuels produce. The first and foremost advantage of solar energy is that it does not emit any greenhouse gases. Solar energy is produced by conducting the sun’s radiation – a process void of any smoke‚ gas‚ or other chemical by-product. This is the main driving force behind all green energy technology‚ as nations attempt to meet climate change obligations in curbing emissions. Italy’s

Green energy is energy that is produced in such a way as to minimize its negative impact on the environment. Traditional energy sources‚ most notably fossil fuels‚ produce greenhouse gases that are believed to be the primary cause of an effect known as global warming or climate change. Sources of green energy‚ such as solar‚ wind‚ geothermal‚ and hydro energy‚ are developed and promoted as alternative sources that make little or no contribution to climate change. Even nuclear energy is sometimes
