Renewable Energy by NEERAJ KULHARI https://padlet.com/neeraj_kulhari/lfews0e9ovqs Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services. en-us 2019-07-04 10:54:02 UTC 2019-07-04 11:58:51 UTC hello@padlet.com Biomass Energy dhillonramneek https://padlet.com/neeraj_kulhari/lfews0e9ovqs/wish/370201477  Biomass is organic material that comes from plants and animals, and it is a renewable source of energy.  Biomass contains stored energy from the sun. Plants absorb the sun's energy in a process called photosynthesis. When biomass is burned, the chemical energy in biomass is released as heat. Biomass can be burned directly or converted to liquid biofuels or biogas that can be burned as fuels.
Examples of biomass and their uses for energy
  • Wood and wood processing wastes—burned to heat buildings, to produce process heat in industry, and to generate electricity
  • Agricultural crops and waste materials—burned as a fuel or converted to liquid biofuels
  • Food, yard, and wood waste in garbage—burned to generate electricity in power plants or converted to biogas in landfills
  • Animal manure and human sewage—converted to biogas, which can be burned as a fue

Each day, around the world, wind turbines are capturing the wind’s power and converting it to electricity. This source of power generation plays an increasingly important role in the way we power our world.  Wind turbine installations continue to grow throughout the world. According to the Global Wind Energy Council, there was over 360,000 MW of installed capacity across the globe at the close of 2014. Leading countries include: China, the United States and Germany.  The potential of offshore wind continues to grow.  While Europe is leading in offshore wind development, with 91% of the offshore installed base, the demand is growing as technology improves and costs go down.  In the United States, GE technology is being used in the country's first offshore wind installation in Block Island, RI.    Wind energy is plentiful, readily available, and capturing its power does not deplete our valuable natural resources. In fact, wind turbines can help to counter the detrimental effects of climate change. The Global Wind Energy Outlook projects that by 2030 wind energy will offset 2.5 billion tons per year of carbon dioxide. This is equivalent to taking 530 million cars off the road each year or avoiding the use of 4.6 billion barrels of oil globally. This would even offset emissions from 525 coal-fired power plants in one year.

Many people today think that because wind is “different,” it is bad for the electricity grid. The reality is that many places today operate at very high levels of wind, while still keeping our lights on!

All power sources need backup power support and no single energy technology can satisfy 100% of the electricity demand. The electricity grid copes with large fluctuations in energy demand on a daily basis, overcoming changes as small as turning lights on to as large as AC units ramping up as people return home from work. Wind plays a role in the grid, helping to support ever-changing demand.
Today, wind turbine owners benefit from well-established wind forecasting technology, and advanced wind plant siting. These advances help wind turbines capture more wind, generate more electricity, and serve as a valuable power generation resource

Due to the marginalised using of resources it is high time that we need to exploit such resources
