Today`s Issue of Energy Crisis

Nowadays, energy has been described as a basic need in human life. For example, when driving to work, I need electricity from using a computer to lighting, using air conditioning, etc. In this example, it is clear that we need a lot of electrical or petroleum energy to complete it. Today's industry is becoming more and more developed, and the energy demand for industrial development is also extremely great. (Colin A. Carter and Henry I. Miller, 2012)The energy on Earth is limited, so it has triggered an energy crisis.

The energy crisis is a severe shortage of energy supplies in the economy. (Richard A. Simmons, 2014) It usually refers to a shortage of oil, but also to electricity or other natural resources.

The crisis usually affects the entire economy, and many recessions are caused by some form of energy crisis. (U.S. Environmental Protection Agency, 2013)In particular, the production cost of electricity rises, which increases manufacturing costs.For consumers, rising gasoline and diesel prices for cars and other vehicles have led to reduced consumer confidence and spending, increased transportation costs and higher overall pricesю

What caused the energy crisis? The energy crisis is the result of many pressures on our natural resources, not just one.

Due to excessive consumption, fossil fuels such as oil, natural gas and coal will be under pressure, which will cause pollution, which will put pressure on our water and oxygen resources. In addition, there is another reason: in most parts of the world, people do not realize the importance of energy conservation.

For example, fans and lights are still on when not in use; private cars are still driving on short distances, etc. On the other hand, the global population is increasing, so the demand for energy is also increasing. So how to alleviate the energy crisis? Other energy resources to replace oil, in addition to coal. Examples are steam, solar and wind energy. Specifically, solar energy is an obvious solution because it is cost-effective and immediately available.

Today, homes with solar panels on the roof can immediately generate their own solar energy to generate electricity. Also, buying energy-efficient products is a good way: use LEDs instead of traditional light bulbs. (U.S. Environmental Protection Agency, 2010)LEDs consume less power and last longer. Strengthen carbon emissions regulations and restrictions, promote green manufacturing and construction projects, and provide funding for research into hybrid and more sustainable technologies.

Another way is to use biofuels. Biofuels can be produced from a variety of advanced feedstocks, including cellulose sources, and may eventually be produced from algae. Cellulose raw materials can be agricultural residues, such as corn straw, wheat straw, or forest residues, or specialized energy crops such as switchgrass, poplar, and willow. （Wallace E. Tyner，2012）These feedstocks can be converted into biofuels through biochemical or thermochemical or hybrid processes.

The final product of biochemical conversion is usually ethanol. Thermochemical or hybrid conversion processes can produce a variety of biofuels, including green diesel, jet fuel, and more. Today, due to the mixed walls discussed above and many other reasons, people are more interested in the conversion of cellulosic materials\nHuman desire and the limited energy of nature are contradictory. With the growth of the world economy, the improvement of living standards, the continuous increase of the population, the human demand for energy is growing, and the constraints and bottlenecks of energy resources are becoming increasingly prominent. Only by finding the perfect solution can we not run out of resources on the planet.
