    Well, nowadays mankind is facing various global problems. Some of them are ozone layer depletion and global warming, deforestation, desertification,  overpopulation and world famine, incurable diseases, species extinction, ice melting and shortage of fossil fuel resources. And , therefore, scientists are working at such problems as finding and using alternative sources of energy, learning how to save and conserve energy, creating highly effective systems of communication, recycling and reusing materials, creating new materials, finding the cure for incurable diseases like cancer, AIDS, heart and vessels problems, drug addiction, cloning.  Besides, scientific minds are working hard at exploring the underwater world, studying the first humans and ancient civilizations, UFOs and the possibility of alien visits, the possibility of colonizing other planets. 

I'd like to speak about alternative sources of energy in detail.

Well, every day, the world produces carbon dioxide that is released to earth's atmosphere and which still be there  in one hundred years time.  

This increased content of Carbon Dioxide increases the warmth of our planet and is the main cause of the so called "Global Warming Effect". One answer to global warming is to replace and retrofit current technologies with alternatives that have comparable or better performance, but do not emit carbon dioxide. We call this Alternate energy.

By 2050, one-third of the world energy will need to come from solar, wind, and other renewable resources. Climate change, population growth, and the fossil fuel depletion mean that renewables will need to play a bigger role in the future than they do today. Alternative energy sources are renewable and are thought to be "free" energy sources. These include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, Hydroelectric Energy sources. Combined with the use of recycling, the use of clean alternative energies such as the home use of solar power systems will help to ensure man's survival into the 21st century and beyond.
