What is renewable energy? After the Great East China Sea earthquake, what happened at the Fukushima Daiichi nuclear power plant shocked the world, and then the tsunami hit Japan. Everyone is waiting to understand the extent of the global impact of this terrible disaster. On the one hand, it raises global awareness and understanding of alternative energy issues. For some time, we have heard that fossil fuel supplies on Earth are already being consumed, not to mention their impact on global warming from greenhouse gases.
Renewable energy is energy from natural resources such as sunlight, wind, agricultural residues, firewood, tides, rain, plant growth, heat generated in the depths of the earth, and even waste. Solar energy is the energy produced by the sun. Hydropower is the energy produced by water. Ocean heat is the energy from waves and tides. Geothermal energy from magma, heat, dry rock, natural geysers and water springs. Biomass becomes a source of energy when burned. Biomass is animal waste, biodegradable waste from cities, firewood and crop residues. These sources are all renewable, which means they happen naturally and constantly. They can be exhausted or exhausted. They are available locally and reduce emissions. The use of these energy sources reduces chemical, radioactive and thermal pollution. 16% of the world's energy consumption comes from renewable sources. It actually replicates traditional fuels in different fields, such as power generation, hot water/space heating, engine fuels and rural energy services.
The question of what is renewable energy has also raised concerns about climate change. In addition, there are increasing oil prices and peak oil prices. Government support from countries around the world has been driving the increase in renewable energy legislation, grants, incentives and commercialization. They are studying this issue to reduce our dependence on oil and other polluting fossil fuels. The 2011 International Energy Agency's forecast includes that solar generators will produce most of the world's electricity in the next 50 years. This will greatly reduce greenhouse gas emissions that are harmful to the environment.
Because of its sustainability, its source can be relied upon for many years to come. We will enjoy more cost effective and efficient power. Renewable energy is also known as green energy. These environmentally friendly energy sources are essentially free of pollution compared to fossil fuels such as petroleum because they emit neither toxic waste nor greenhouse gases.
Looking ahead, we will hear more and more information about renewable energy. Addressing the growing awareness of electricity bills and global change will pave the way for communities to provide small, reliable steps to achieve energy savings.
