Final answer:

Investing in alternative energy is crucial for sustainability, and incentivizing private firms can drive innovation and cost-efficiency.


Explanation:

The government should invest more in the development of alternative sources of energy due to the key role of energy in sustainability. Developing efficient, environmentally-friendly energy sources is crucial to address current issues of space, waste, and cost associated with traditional energy sources like fossil fuels.

By providing incentives to private firms for research and development in alternative energy, the government can promote innovation more effectively than if it were to solely carry out the spending itself. This approach can encourage competition, reduce costs, and stimulate technological advancements in the renewable energy sector.
