Final answer:

David and Karen use solar panels to help power their home. The invention that allowed nineteenth-century manufacturers to power machinery in smaller settings was the internal combustion engine. Wind energy and hydropower are both powered by the sun, which is their original source of energy.

Explanation:

David and Karen use solar panels to help power their home. In the nineteenth century, internal combustion engines enabled manufacturers to power machinery in places where steam engines were too big to be used. There are various alternative energy sources which can be used instead of coal to generate energy; these include biodiesel, oil, coal, and hydropower. The original source of energy that powers both wind energy and hydropower is the sun, which drives wind patterns through uneven heating of air masses and facilitates the water cycle affecting hydropower production
