| What does Sustainable Energy mean? Why is this Essential? | -Means that we give enough Energy Today, and Ensuring that the Future will also be able to Reach Demand
-Key today as Demand is Rising up Fast, but Non-Renewables are Running out
-Humans will need to Exploit Better, Find Renewables, or be more Efficient |
| What is a Carbon Footprint? | -This is just measuring the Amount of Greenhouse Gases that an Individual, Community, Company or even Nation Produces |
| -What are Direct and Indirect Emissions? | -Direct Emissions are made from Products that USE Energy
-Indirect Emissions are made when MAKING things we Buy [Clothes, Food, Water] |
| How can Sustainable Design Conserve Energy? | -Insulation --> Less Energy for Homes needed
-Modern Boilers --> Efficient - less Energy Wasted
-Solar Panels --> Provide Renewable Energy - low Carbon Footprint
-Electric Transport --> More Efficient
-Biofuel --> Waste Products -> Biofuel -> Re-Used |
| How can Demand Reduction Conserve Energy? | -Reducing Demand is done by trying to Persuade People to Lower Energy Usage by perhaps Tax Relief and Exemptions
-Better Public Transport & Use of Cycling and Walking & Congestion Charges [London] --> Less Demand for Energy in Transport
-Smart Meters in Houses allows People to see how much Energy they are Using and therefore the Cost of the Electric Bill. |
| How can Using Technology to Increase Efficiency Conserve Energy? [No Brainer] | -Energy Saving Light Bulbs --> More Efficient and can last Longer [Bans also be put on Inefficient Products as well - EU]
-Hybrid Cars --> Combines Electric Power & Fossil Fuel = Efficiency
-Regenerative Braking --> Store Energy lost as you Break - Can be Reused [and therefore saves Petrol from being used up]
-Manufactures making more Efficient Engines because of Legislation and Fuel Costs.
-Power Stations using Gas and Combined Cycle Gas Turbine Tech -> Energy lost as Heat is now used to make Steam [Which turns Turbines..] This makes 50% more Electricity from Same Amount of Fuel |
