level questions: Increasing Renewable Energy Supplies

QuestionAnswer
Why is Renewables a Good Option?-They will not Run Out -Less Waste Products -Less Maintainece
What did Costa Rica do in 2018 regarding Renewables?-For 300 Days, they ran on Renewables
Solar. What is it, Advantages and Disadvantages. Example-Energy from Sun used to Heat Water or Make Electricity A: Solar Cooks = Cheap. Energy can be in Excess = Profits D: Cells for Converting Solar --> Energy is Expensive. Sunlight is Needed so Cloudy and Night times are Peak E: Morocco has the Noor Complex [Largest in World] and gives 1+ Million Electricity
Hydro. What is it, Advantages and Disadvantages. Example-From Falling Water OR Trapped by Dam which is Allowed to fall through Tunnels that spin Turbines --> Electricity A: Flexible and Efficient - They can be Adjusted to suit the Energy Demand at the Moment D: Habitats and Communities Threatened from Flooding - Reservoir. Expensive to Make E: China has the Three Gorges Dam [Largest in World] and makes more than USA & Canada Combined
Geothermal. What is it, Advantages and Disadvantages. Example-Water Pumped to Ground = Steam. Turns a Turbine = Electricity. Steam also for Heating Houses A: Cheap and Reliable - Little Construction really Needed D: Only works Best at Tectonically Active Areas E: Iceland has 87% of Heating from Geothermal Energy
Tidal. What is it, Advantages and Disadvantages. Example-Currents or Water Level Changes --> Turbines turned --> Electricity! A: Can be Predicted, as Tidal Cycles are Regular D: Unable to make Constant Energy. Also Expensive E: Proposed Swansea Bay Tidal Lagoon make Energy for 120,000 Homes
Wave. What is it, Advantages and Disadvantages. Example-Waves can turn Turbines [All Energy Sources, ish, will Turn a Turbine] A: Usable in Winter so it can Pair with Solar D: Expensive E: Wales may see Wave Energy Projects as well as Cornwall
