Answer to Question 1

Biofuels include biodiesel, which supplements petroleum diesel in diesel engines and solid biofuels such as cellular walls of plants can be used to supplement coal in electrical power stations.

Answer to Question 2

Large dams can release water to generate power as needed. The reservoirs provide recreational areas and flood protection. Negative impacts include loss of land including farmland, destruction of wild rivers and wildlife habitat, fish migration and loss of spawning grounds, silt buildup, water quality issues and loss of nutrients for land below the dam. The reservoirs can be a natural breeding ground for mosquitos and certain snails, which carry disease.
