Renewable Energies


There is no other way to change the worst climate condition of our Eco-System without taking brave steps: nearly 40% of US CO2 pollution comes from power plants burning fossil fuels. Similarly, in every other developed country, they are all using an immense amount of energy resources to accomplish their needs in the field of energy. Fossil Fuels are being burnt in large amounts to meet the requirements of modern-day energy. And this behavior of countries towards meeting their energy requirement is certainly not in favor of our Climate or Eco-System. But we can turn things around. But the question is how we can change all this and turn things around since it is not an easy task to do. But if we decide to do something no hurdle will be in our way.
Renewable energy is that type of energy which we can use again and again without any bad effects on our environment. There are many sources of renewable energy that exist the thing is to adopt them. It minimizes carbon pollution and has a much lower impact on our environment. Giving people more access to renewable energy can allow them to reduce their own energy bills while reducing stress on the grid stations and demand for fossil fuel power. This can also save money as well as allow us all to breathe cleaner air.

Types of Renewable Energy:

  • Solar Energy: One very comprehensive solution to reduce global warming caused by energy could be the use of SOLAR ENERGY at commercial and house level. Humans have been using energy coming from the SUN from the very first day to cook crops, stay warm and for dry fruits. According to the National Renewable Energy Laboratory "More Energy falls on the earth in one hour then is used by everyone in the world in one year." So, why waste this much amount of energy? Sun is a natural source of energy and the energy coming through its rays can be used for various purposes e.g. for powering Industry, homes and also at other workplaces. Solar Cells are specially designed for this purpose. Solar Cells or Photovoltaic Cells are made of Silicon Chips or other materials that transform Sunlight directly into electricity. These can be used to produce energy for homes or for the industry also. This is a very cheap and easy method and if adopted it can reduce the use of other costly methods to generate electricity.

  • Wind Energy: Air is the GODs greatest blessing on man. It is the only thing that requires for human survival without it everything in this whole universe might face extinction. Where it is that much necessary for human survival is also a source of renewable energy. It can be used to produce Electrical energy by placing windmills in the coastal areas because the speed of air in those areas is relatively higher than in other areas. Wind energy turns a turbine blade which is connected to an electrical generator that produces electricity when they are rotated by Winds at high speed. This is probably the cheapest way to produce electricity more than 6% of US energy comes from windmills.

  • HydroElectric Power: Hydropower is one of the largest renewable energy sources in the world. It relies on water mostly high-speed water coming from a big height like in DAMS. Hydropower method is used to generate energy in more than 140 countries of the world with Asia Pacific region countries contributing to more than 32% of the world's global hydropower generation by the year 2010. Water contributes more than 70% of our whole Eco-System and if it is used in a correct manner it can be helpful for producing more energy and controlling global warming on a large scale. China is the country with one of the largest producers of hydropower with a total production of 721 Terra Hours by the year 2010.

  • Tidal Power: Tides are the rise and fall of oceans level by the combined effect of the gravitational pull of Sun during day and Moon during the night. It is a natural process happening from centuries causing the sea level to rise naturally. But, How this natural rise and fall in waves can be used to generate energy? Here's how. Scientists of the 20th century have discovered a way to generate electrical energy using these tides it uses special types of generators or paddles to produce electrical energy in the areas where the tides are usually high. Tidal energy is still in its infancy. The amount of energy produced by tides is still very low but scientists are working to improve their efficiency.

Climate action is not just a defensive play, in order to coup with it we need to take some brave steps. We have to see every challenge as an opportunity to modernize our power sector and build a low-carbon economy that will fuel growth for decades to come. This is the only possible way to make our world a heaven for the coming generations. We have to replace fossil fuels as an energy source with green power or more precisely renewable energy sources because this is the time to do the right thing to save our next generations from the worst outcomes of climate change. This is the most important action we can take to address the impacts of climate change on health and to reduce pollutants that can lead to disease.

Renewable energies offer so many benefits, from changing air and reducing the pollution, to lowering prices and taking us off the destructive boom-and-bust a merry-go-round of fossil fuel prices.
