The types of energy we use and how we use them are central factors in determining to what extent we are moving towards a more sustainable society. Our dependence on non renewable fuel causes pollution and environmental degradation.
The world has to solve this problem on a sustainable basis. It needs a transition from its current unsustainable energy use to a future powered by entirely renewable energy supply.
Only by making such a transition will we be able to avoid the very worst impacts of climate change.
This transition is not only possible but also cost-effective, providing energy that is affordable for all and producing it in ways that can be sustained by the global economy and the planet. It surely pays off as once the infrastructure for energy supply has been established; the costs for the renewable system are markedly lower compared to a continued fossil fuel system.
Such a future is within our reach, and it can be achieved.It’s about finding ways to do more with less. Energy conservation is something everyone can embrace – we simply need to start making wise choices
We could construct green buildings that require virtually no energy for heating or cooling.
• Switch from big, powerful, “gas-guzzling” private cars to more efficient forms of transport.
• Choose efficient alternatives over energy-hungry appliances clog that the market.
• Manufacturers could use far less energy by reassessing their materials and processes.
• Businesses could work towards developing a green economy.
World leaders need to take action on the energy crisis that is taking shape before our eyes. What is required is nations to cometogether and establish a global mechanism assessment of supply and demand, fund R&amp;D, technology transfer to poorer nations.It is the time to develop long-termsolutions to the world’s energy needs which will benefit all humankind
India’s significant and sustained economic growth, urbanization, rise in per capita consumption, and spread of energy access is placing enormous demand on its energy resources.
At the same time, a very large proportion of Indian citizens around 50% continue to live with no access to electricity and other forms of commercial energy.
The increasing trend though in the number of green initiatives in the past few years is encouraging. From green tourism in Goa to alternative green energy sources being developed across the length and breadth of the country, the path for a more sustainable future is being laid
Wind, solar, hydro and biomass are some of the alternative sources of energy. However, there are many other technologies and means which are at the nascent stage and are used for producing power.Non-conventional energy sources are those which are natural, inexhaustible and renewable.
They are inexpensive in nature and were in use much before conventional sources like coal oil or natural gas.For instance, windmills were used to grind grains and pump water.
Government support and emphasis on clean sources of energy have also resulted in new capacities being built on the basis of such sources.
