A city is concerned about global warming and smog. It wants to reduce the impact of its use of fossil fuels. Explain how the city could use technology to reduce fossil-fuel use by changing (a) its transportation, (b) its buildings, and (c) services for city residents

a) Increasing the toll for non carpoolers will motivate people to carpool and therefore will decrease the number of cars in the road burning fossil fuels.

b) Tax breaks for buildings that use solar panels for energy. This reduces fossil fuels burned for electricity.

c) The city can increase the amount of city transportation available. While this may seem counterproductive because the amount of buses or trains or boats burning fossil fuels increases, by doing this more people will have easy access to public transportation and it has been shown that public transportation is more effective in reducing fossil fuel usage per head. Providing more options of public transportation will increase their usage and therefore will over decrease the amount of fossil fuel burned by individiuals which will overall decrease fossil fuels burning.

the answer would be b i believe
