| 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 |
| Wind. What is it, Advantages and Disadvantages. Example | -Wind Turbines spin making Electricity
A: No Greenhouse Gases made so its Carbon Neutral
D: Varied Energy Source as Wind isn't Constant. Also the NIMBY Movement
E: Denmark ran an Entire Day on Wind |
| Biomass. What is it, Advantages and Disadvantages. Example | -Wood, Plants or Animal Waste burnt for Power or Biofuels
A: Little usage of Technology, LIC's Like this
D: Renewable if its Managed Sustainably
E: USA made 1 Mil Barrels of Biofuels |
