Transportation
Fuel economy: is measure of how many miles you can travel, on average, for every gallon of gasoline that you use (miles per gallon)
Corporate Average Fuel Economy (CAFE) to improve the average fuel economy of new cars and light trucks, vans, and sport utility vehicles (SUVs) in the US
New energy-efficient vehicles
- Gasoline-electric hybrid cars: small gasoline -powered engine and a battery-powered electric motor used to provide the energy needed for acceleration and hill climbing
- Plug-in hybrid electric vehicle: small gasoline-powered motor kick in, recharges the battery, and extends the driving range to 600 km or more
- All-electric vehicle: runs on a battery only
CO2 emissions reduced by replacing vehicles with hybrid, plug-in hybrid, and all electric vehicles.

Buildings
biggest energy cost in your home are: heating, cooling, electronics and appliances
Home insulation: homes requires it to isolate the inside and outside and prevent heat from escaping and heat entering
To save energy and money: insulated windows, seal gaps around the window frame, insulate the building roof and walls In existing buildings: heat interior spaces more efficiently, heat water more efficiently, use energy-efficient appliances (computers, lighting) and stop using standby more
Energy star: voluntary program launched by US environmental protection agency (EPA) and manage now by EPA and the department of energy. Helps businesses and individuals to save money and protect the environment through energy efficiency
Green architecture uses old and new technology to save energy. Green roofs can reduce the costs of heating and cooling by absorbing heat in summer and retaining heat from winter
Case Study: Germany 80% of the countries cell installations are owned by homeowners and businesses (income from feed in tariff which requires utility companies to buy electricity produced by homeowners and businesses from renewable energy sources at a price that guarantees a good return and to fee it into the electric grip)
