Sustainable future through solar and wind energy

           With people’s insatiable consumptive habits, we are facing some real problems such as polluted environment or people losing their home because of sea level rises etc. To produce profit without destroying our natural resources and create a sustainable future, people came out with the idea “sustainable development.” For our sustainable future, people should use solar energy system and wind power energy. Through these energy system, people can use energy unlimitedly, keep our Earth unharmed and save money.

             So far, people are depending on natural resources a lot, especially on fossil fuels. The problem is that natural resources including fossil fuels, are limited. They are in danger of running out. However, solar energy and wind energy is limitless. The sun is an unlimited energy source that produces massive heat and light energy. Wind is also an unlimited energy. Since the sun and air will always be here, people can use this powerful energy without worrying.

             With these energies, people can also save our planet and make our future sustainable. The solar energy and wind energy are non-polluting energy source that doesn't emit green-house gases and carbon. By using solar panels, people can use energy without limits while saving our land. In addition, with wind power generation, it is estimated that 1.5million tons of carbon dioxide production will be reduced by 2020. These eco-friendly energies are effective in protecting our planet and so these improved systems will affect our future generation in substance

The most powerful and positive factor of these eco-friendly energies is their economic benefit. As a real example, my friend’s grandparents are actually using solar energy through solar panels. Before using the solar panels, their heating bills were very expensive and costed about 300,000 won. However, after they installed the panels, the cost reduced until 3000 won. As installing the panels are expensive, it is difficult for regular homes to install those panels on their own. To promote people and make sustainable future, government’s economic aid will be necessary.

Because of our selfishness and shortsighted greed, our planet has been devastated. For our future generation, promoting a pleasant environment is essential. To make a sustainable future, sustainable development through solar energy and wind energy is necessary. People will be able to make a better environment with these limitless, eco-friendly, and economic energies.
