Countries around the world are considering various possibilities to reduce the emission of greenhouse gases. which step would be a cost-effective and realistic measure for them to adopt?
a) build more thermal power stations.
b) use coal to heat buildings in winter.
c) increase the efficiency of coal power stations.
d) burn firewood, instead of fossil fuels, as a source of energy.

The best answer to the question stated above would be letter  D) Burn firewood, instead of fossil fuels, as a source of energy.

Human activities like burning coal, oil, and natural gas to generate energy for power, heat, industry, and transportation, produce greenhouse gases. One way in reducing emissions would be to switch from fossil-fuel-based power to alternative sources of energy, such as nuclear, solar, and wind.
