Solar passive and active
Wind generation
Hydrogen power
Using Solar Energy to Provide Heat and Electricity
Passive solar heating
Active solar heating
Using Solar Energy to Provide High-Temperature Heat and Electricity
Solar thermal systems
Photovoltaic (PV) cells
Producing Electricity from Moving Water
Large-scale hydropower
Small-scale hydropower
50% of West Coast electricity
7% of US electricity
20% of World s electricity
Major environmental impacts
High construction costs
Impacts of hydropower on salmon and other riverine spp.
Pollution
Disruption of water flow
Loss of biodiversity
Invasive species
Impacts of hydropower on Species and People__
Dams can provide many human benefits but:
Disrupts ecological services rivers provide; e.g. 119 dams on Columbia River have caused a 94% drop in wild salmon; removing hydroelectric dams will restore native spawning grounds
Displaces millions of people worldwide as reservoirs flood traditional homelands
No room for expansion in the US
Producing Energy from Biomass
Biofuels
Biomass plantations
Crop residues
Animal manure
Biogas
Ethanol
Methanol
The Solar-Hydrogen RevolutionExtracting hydrogen efficiently
Storing hydrogen
Fuel cells
Geothermal Energy
Geothermal reservoirs
Dry steam
Wet steam
Hot water
Molten rock
Hot dry-rock zones
Creating a Sustainable Energy FutureIncrease fuel efficiency standards for vehicle, appliances, buildings
Tax and other financial incentives for energy efficiency
Subsidize renewable energy use, research and development
Internalize externalities for fossil fuels
By 2050:
Increase renewable energy to 50%
cut coal use by 50%
phase out nuclear altogether
conclusion
Thus we see about the renewable energy sources , it s types , applications , merits and demerits

Abstract:
Renewable energy is energy generated from natural resources such as sunlight, wind, rain, tides, andgeothermal heat, which are renewable (naturally replenished). While most renewable energy projects and production is large-scale, renewable technologies are also suited to small off-grid applications, sometimes in rural and remote areas, where energy is often crucial in human development.
