Sanjay and his family want to cut back on their use of non-renewable resources at home. They are thinking of an alternate way to heat their home without adding more greenhouse gases or pollutants to the environment. Which renewable resource would NOT fit into their plan? A) solar power B) burning wood C) constructing a wind turbine D) generating hydroelectric power

The correct answer is letter B, burning wood. This is not a renewable resource of energy as its by-product involves the release of greenhouse gases that can still be harmful to the atmosphere or to the environment in general. All the other choices are good sources of renewable power because they harness the power of naturally occurring materials found in their space.
