A combination of different but complementary energy generation\nsystems based on renewable energies or mixed (RES- with a backup of Liquefied\nPetroleum Gas (LPG)1\/ diesel\/gasoline genset), is known as a hybrid power\nsystem (\u201chybrid system\u201d).<\/li><li>Environmentally friendly power\ngeneration technologies will play an important role in future power supply. The\nrenewable energy technologies include power generation from renewable energy\nsources, such as wind, PV(photovoltaic), MH(micro hydro), biomass, ocean wave,\ngeothermal and tides.<\/li><li>Since the RE resources are intermittent\nin nature therefore, hybrid combinations of two or more power generation\ntechnologies, along with storage can improve system performance.<\/li><\/ul>\n\n\n\n<p><strong>Challenges\nfacing by renewable energy:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>It relies on\nintermittent sources, producing energy only when the sun is shining or wind is\nblowing, its output is constrained to specific hours of the day<\/li><li>Its use leads to lower\nutilization of transmission lines. This can create issues in matching peak\npower demand with renewable output (e.g. in evening hours when solar energy is\nnot available), and raise costs of transmission.<\/li><li>While the\ncost of renewables has fallen significantly in the past few years, a major\nissue with renewables such as solar and wind energy is their intermittency in\nnature.<\/li><li>Solar and wind power are not as easy to\ncontrol as traditional fossil fuel plants, so power grids need to become\nflexible enough to handle last-minute changes in power generation.<\/li><li>Distance is also an issue. In India, six\nstates in the western and southern regions&nbsp;account for 80 percent&nbsp;of all of the country\u2019s currently\ninstalled solar capacity, but only 38 percent of power demand.<\/li><li>Renewable\nEnergy as deployed today helps meet an energy need (kWh), but doesn\u2019t help meet\nthe peak by contributing capacity (kW) at the right time, which is India\u2019s main\nchallenge.<\/li><li>Rooftop solar is far,\nfar behind schedule to meet the 40GW goal.
