Energy makes our lives simpler for us. The energy industry produces for us heat, light and force. Since our needs are not going to get fewer in the next twenty years as the country’s economy and every other field is digitally driven,…

Man will devise ways to substitute the materials endangered by exhaustion like fossil and nuclear energy sources, with renewable energy sources. Renewable energy will continue to combat “greenhouse gas emissions within the power sector” (Moselle, Padilla and Schmalensee 160). This paper discusses important sources of green energy, and why these sources are known as renewable sources of energy.
First of all, it is important to describe the types of renewable energy sources. Sun power, wind power and water power are three main sources of green energy. Sun power produces solar energy, and is a very powerful form of energy. It has been there since ages, and will remain there till the end of the world, providing heat and light energy to all forms of lives- animals, plants and humans. Solar energy is called renewable energy due to a variety of reasons. First, when modern technological methods convert solar energy into electricity, no smoke is produced. So, there is no production of carbon dioxide and other toxic chemicals in the air. Also, the supply of solar energy is not limited, so, there is no worry about running out of energy. However, solar power cannot always be relied upon, as there is no sun in the night or in cloudy weather. Solar cells and solar panels are two main devices that convert solar energy into electrical energy. Solar cells, also known as photovoltaic cells, are found in smaller devices as calculators, and are also used for bigger purposes like in road signs. Solar thermal power plants and the parabolic trough systems are modern technological methods that use solar panels that trap in sun power to heat up water that, in turn, produces electrical energy. Another source of renewable energy is water, called hydro-power. Since water in motion produces kinetic energy, this scientific fact is used by hydro-electric power

Consequences like global warming and climate changes have become matters of serious concerns. As energy prices are raising and pollution affecting the earth badly, people are concerned to make more efficient usage of energy.
Technology makes use of knowledge for practical purposes. In the contemporary age, issues like global warming and sustainable development have become the focus of discussion everywhere in the world. There are considerations about the diminishing natural resources and the present generation is concerned about their own future as well as that of the future generations.
Such an impression stemmed from the position taken by Obama during the election campaign and the growing desire to reduce dependence on foreign oil and volatility in its price. (1). Down the road it will be interesting to evaluate the actual progress in the direction of reducing dependence on oil based on the green energy initiatives of the Obama administration.
In fact, there is already a sharp contrast between the two powerhouse countries. Whereas the United States is heavily burdened by debt, China enjoys the distinction of having the most Gross International Reserves (GIR) Thus, in effect, the US has become the highest debtor while China has become the biggest creditor (Financial Ranks 2008).
Evidently, many industrially developed nations tend to export their trash to third world countries today. This unfair practice will cause dreadful impacts to the ecosystems as a whole. Recently, some energy companies have developed effective ways for generating energy from the garbage through the process of recycling waste materials.
This phenomenon has triggered a chaos in the minds and hearts of people globally. The race to accumulate resources has forced prices in commodities to sky high. Even basic food items are at their highest. One of the sectors most affected by this
The solution to this problem is alternative energy (LePoire, 2011).
The US government should increase the incentives to attract alternative energy investment. Increase in incentives will increase the alternative energy sources
They have either ‘sold their ideas to energy producing firms or issued it to the public to help them come up with green energy. Fossil fuels when burnt to produce energy emit carbon dioxide, which is a threat the ozone layer that protects humans from harmful radiations
The early improvement of sun-powered advancement started in 1860’s and was determined by the assumptions that natural occurrence of coal will get utilized and will become rare. Nonetheless, improvement of sun oriented innovations stagnated in the early twentieth century notwithstanding the expanding accessibility, economy, and utility of coal and petroleum.
