mention the alternate sources of energy used in today's world
Answers
Solar Power
What better way is there to reach Type I status, than to get your energy straight from the source—solar power involves harnessing the power of our sun. From photovoltaic (PV) cells that capture photons and convert them into electricity, to solar thermal energy (STE) that makes use of the sun’s heat, solar is one of the most promising alternative energy sources on the market today.
Wind Power
For thousands of years, humans have harnessed the wind to push sails, mill grain, and pump water. Today, windmills use turbines to convert rotational energy into electricity that can reliably flow into to a grid. On a larger scale, wind farms are projected to provide as much as 20% of global electricity production by 2030.
Biomass
and biodiesel are among the most widely used renewable energy sources. In stark contrast to fossil fuels which are produced by geological processes that can take millions of years, biomass typically refers to biofuels that are obtained through biological processes such as agriculture and anaerobic digestion. Fuels like bioethanol from corn or biodiesel from transesterification of plant oils burn cleaner than conventional fossil fuels and can help countries stay within their carbon budgets.
Tidal Power
The rise and fall of the tides is steady and predictable, making tidal power a viable alternative source of energy for regions where high tidal ranges are available. The Rance Tidal Power Station in France, is the world’s first large scale tidal power plant, and used turbines to generate electricity, much like a hydroelectric power does for a dam. More recently, CETO, the grid-connected wave power station off the coast of Western Australia used a series of buoys and seabed pumps to generate electricity.
Geothermal
Roughly 1.4 x 1021 joules of heat energy flows to the Earth's surface every year. Regions with high levels of geothermal activity like Iceland and Indonesia can tap into this geothermal energy available in magma conduits and hot springs to spin turbines that generate electricity or provide natural heating to homes.
