Creation of new technologies to protect environment

Nowadays, with the development of science and technology, an increasing number of issues have been brought to the world. The issue of environment becomes one of main problem in the world.

 It is obviouly that there is  a strategy which is the use of renewable energy technologies integrated into the modern cities, such as solar water heaters, electric vehicles and solar heating or cooling system. According to International Energy Agency, renewable energy technologies are beneficial for environment due to replacing non-renewable resources and can be often assembled relatively conveniently in response to changing demand. In recent, the reasons why solar energy is widespread and acts an obbligato role in modern cities is because there will never be scarce, it is free for all of users and the most important factor that solar energy is completely clean competing with non-renewable energy. International Energy Agency points out solar heating system can save 30 present of energy as well as expand more building’s space heating requirements comparing with conventional fuels machines. For example, most of public housing installed solar heating system replacing natural gas or oil heating systems in Canberra, Australia. It is reported that the appliance has achieved an energy efficiency by saving 200 Australian dollars per annum with an additional building cost of 600 Australian dollars.

 Therefore, the strategy, which involves significantly the long term development to environment and finite resources in the earth, can be seen as the most important strategy, as without it, the earth will be deteriorated environmentally and consumption of energy will be accelerated.
