Energy is one of the most important resources for mankind and its sustainable development. Today,
the energy crisis becomes one of the global issues confronting us. Fuels are of great importance because
they can be burned to produce significant amounts of energy. Many aspects of everyday life rely on fuels,
in particular the transport of goods and people. Main energy resources come from fossil fuels such as
petrol oil, coal and natural gas. Fossil fuel contributes 80% of the world’s energy needs. Most industries
use diesel machines for the production process. In the transportation sector, private vehicles, buses,
trucks, and ships also consume significant amounts of diesel and gasoline. This situation leads to a strong
dependence of everyday life on fossil fuels. However, the growth of the population is not covered by
domestic crude oil production [5-6].Fossil oils are fuels which come from ancient animals and microorganisms.
Fossil fuel formation requires millions of years. Thus, fossil oils belong to non-renewable
energy sources.
The correct answer is B. Increasing the use of alternative energy sources.
Explanation
Alternative energy sources are a term used to refer to renewable energy sources that do not affect the environment unlike fossil fuels and traditional energy sources that cause global warming by combustion of them. Alternative sources of energy use wind, sun rays, water currents, among others to produce energy without causing damage to the air, or natural resources such as water. Therefore, alternative energy sources and the increased use would generate a decrease in global warming, because this occurs due to the extensive use of fossil fuels to generate energy. So, the correct answer is B. Increasing the use of alternative energy sources.
