Hydroelectric: Energy harnessed from the movement of water, rivers, lakes and reservoirs
Wind power: Wind turbines collect wind energy and turn it into electricity
Solar energy: Sunlight is captured in solare powers and turned into electricity.
Tidal power: Tidal energy is a form of hydro power that converts energy from tides into electricity.
Geothermal energy: A geyser can erupt hot water and steam. Steam can be used to power turbines and create electrcity.
How we prevent it:
Humans prevent climate change by planting trees/shrubs/plants to prouce oxygen, switching off and unplugging appliances not in use to save electricity , walking/cycling to help stop pollution, install double lazing so you can use les heat by keeping it in and getting cold out, use energy saving lightbulbs and turning the heat own and putting extra clothing on to save thermal energy bills.
How to increase it:
Humans increase climate change by driving places they could of walked/cycled which helps air pollution, some activites produce greenhouse gases which keep increasing in th atmosphere: Burning fossil feuls: Oil, Coal and natural gases, cutting down and burning trees creates pollution from the smoke, makes less oxygen and produces arbon dioxide.
Weather effects crops, plants, animals and humans.
Storms, floods and droughts.

Process of a power plant
the fuel is burned to boil water to make steam
the steam makes a turbine spin
the spinning turbine turns a generator which produces electricity
the electricity goes to the transformers to produce the correct voltage
How a wind turbine creates electricity
As the wind blows, it transfers some of its kinetic energy to the blades, which turn and drive the generator.
How do wind turbines work
Fossil feul : Coal, oil and natural gases which release carbon into the atmosphere
