In their triangle, each wedge represents a reduction of 25 billion tons of carbon emissions over 50 years (0.5 billion tons/ yr). This means reducing carbon emissions by only 1.4% per year, which seems very feasible. Ideally, given current technologies, each country could find the best methods for addressing its seven wedges. There are many different ways for a country to address each wedge. For example, one country could decide to increase wind power 40-fold to displace coal over 50 years and also decide to increase fuel economy of two billion cars from 30 mpg to 60 mpg over 50 years. In doing so, this country would address two of its seven wedges. Which of the following can countries do to further help decrease carbon emissions by 2056? a. Install carbon capture and storage facilities at coal-fired power plants.
b. Replace gas-fired power plants with coal-fired plants.
c. Reduce electricity use in homes, offices, and stores.
