RENEWABLE ENERGY
SOURCES
Hydropower
harnessing the energy of river currents
using dams to control water flow
harnessing the power of the movement
of oceanic tides to generate electricity
Wind
harnessing the wind as a source of energy
electricity-generating wind turbines
Solar power
electricity and heat are derived from the sun
sun emits energy
solar cells convert the sun’s light into usable energy
ADVANTAGES
no carbon dioxide emissions
virtually inexhaustible
reducing dependence on fossil fuels
slowing down the depletion of natural resources
cutting back on air pollution
DISADVANTAGES
totally depend on the weather
lack the much-needed efficiency
require a huge financial outlay
have high maintenance expenses
manufacturing processes
emit greenhouse gases
dams can disrupt river ecosystems
IMPLEMENTATION
instituting policies aimed at increasing renewable energy
setting renewable portfolio standards
policies that could encourage renewable energy growth
carbon pricing
fuel economy standards
building efficiency standards
