Solar
Pros
- potentially infinite energy supply
- personal electricity supply
- low maintenance costs
Cons
- installation costs
- energy generation only during the daytime
- expensive to store
- take up a lot of space
Hydroelectric
Pros
- water reserves + energy supplies
- great for countries with high rainfall
- on-demand energy
Cons
- installation costs
- risks of flooding
- impact on local hydrology
- build-up of plants reduces storage
Wind
Pros
- potentially infinite energy supply
- versatile (size, number of turbines)
- can supply energy to rural areas
Cons
- installation costs
- spoils the landscape
- potential danger for the wildlife
- unreliable source of energy
Biomass
Pros
- readily available
- constant/reliable energy source
