Identify specific ways in which the transportation and electricity generating sectors could reduce and/or conserve energy in an effort to become more sustainable
What will be an ideal response?
Transportation: Currently, the combustion of oil-derived fuels accounts for 31% of all human-caused greenhouse gas emissions. The use of electric or hybrid cars, and increasing the opportunities for buses and other mass transit options that are more energy efficient, are options moving us in the direction of a more sustainable transportation future. With higher gasoline prices and more stringent regulatory standards being instituted worldwide, incentives are being created for the production of more fuel-efficient vehicles and vehicles powered by alternative energy sources.
Electricity: The existing system of demand-driven generation and distribution of electricity is generally agreed to be wasteful and inefficient. Newer smart grid systems in which real-time pricing is employed (based on consumer high-demand times) and consumers are alerted to when "rush hour" demand periods are occurring, allows consumers to curtail their use and actually consider their electricity consumption in a more realistic manner. With smart grid systems, homes with solar panels would be able to sell their excess solar power back to the grid, or use batteries to store electricity purchased during slack hours for use at peak times.
