0:04 around the world renewable energy use is
0:06 on the rise
0:08 and these alternative energy sources
0:10 could hold the key to combating climate change
0:17 [Music]
0:20 what is renewable energy
0:22 renewable energy is generated from
0:24 sources that naturally replenish
0:26 themselves and never run out
0:30 the most common sources are solar wind
0:34 hydro geothermal and biomass
0:37 over 80 percent of the total energy
0:39 consumed by humans is derived from
0:41 fossil fuels
0:44 however renewables are the fastest
0:47 growing source of energy in the world
0:51 renewable energy has many benefits
0:54 first it can combat climate change
0:56 because it creates no direct greenhouse
0:58 gas emissions the only emissions that
1:01 they produce are indirect meaning those
1:04 that result from manufacturing parts
1:07 installation operation and maintenance
1:10 but even those are minimal second
1:11 second
1:14 renewable energy can decrease pollution
1:15 and therefore reduce threats to our health
1:17 health
1:19 wind solar and hydroelectric systems
1:22 create no air pollution emissions
1:25 and geothermal and biomass energy
1:27 systems emissions are much lower than
1:30 non-renewable energy sources third
1:31 third
1:34 renewable energy is a reliable source of power
1:35 power
1:38 because renewable energy sources are
1:42 well renewable they will never run out
1:45 once built renewable facilities cost
1:47 very little to operate and the fuel is
1:49 often free
1:51 as a result renewable energy prices tend
1:54 to be stable over time
1:56 while renewable energy has many
2:00 advantages it is not without downsides
2:02 it is difficult for renewable energy
2:04 sources to generate power on the same
2:07 large scale as fossil fuels
2:10 building wind farms and dams can disrupt
2:12 wildlife and migration patterns and lead
2:15 to ecological destruction
2:17 both solar and wind energy are
2:20 intermittent they only generate power
2:22 while the sun is shining or while the
2:24 wind is blowing
2:26 batteries can store excess energy for
2:31 later use however they are often costly
2:33 while renewable energy presents some
2:35 challenges it also offers an
2:38 environmentally friendly alternative to
2:39 the greenhouse gas emissions and
2:42 pollution of fossil fuels
2:44 and as advances in technology make
2:46 renewable energy more accessible
2:48 affordable and efficient
2:50 and end to climate change could be
2:53 within our reach [Music]
