Man cannot altogether stop using fossil fuels but moves to decrease energy consumption by developing new technologies designed for energy efficiency is the best way to alleviate the state of the environment.
New Technologies refer to both innovations in production or generation of energy and its actual use. Generation of energy from solar, wind, geothermal, tides and hydroelectric are, currently, being implemented and studied. The graph below shows that new technologies in the generation of energy from renewable resources delivers needed energy but emits less CO2 emissions. US-NASA predicts further decrease in CO2 emissions in the future.
New technologies developed for actual use or consumption of energy seeks to maximize these renewable sources of energy in the three major areas of transportation; industrial energy usage; and, in commercial and residential buildings. This is clearly exemplified in the Modern Refrigerators and the introduction of Electronic Vehicles. The diagram below shows that the energy use per refrigerator decreased by two-thirds since the introduction of new energy efficient refrigerators. The continued study and development of refrigerator efficiency improvements has proven to be a success.
The introduction of Electronic Vehicles according to the research by Micheal Wang, Mark DeLuchi and Daniel Sperling has the effects of lowering the emissions of HC, CO, NO, SO, and particulates. With continued use, they predict a significant reduction in California that will help major air basins in California meet national ambient air quality standards.
It cannot be denied that new technologies decrease pollutant emissions. To be fully effective, according to study conducted by Amit Garg, P.R. Shukla, Debyani Ghosh, Manmohan Kapshe and Nair Rajesh, laws and governments must give full support to the endeavor.
