Which factor most constrains the global scalability of large-scale hydroelectric power compared to solar or wind energy?

Answer

Global scalability of large-scale hydropower is fundamentally limited by the finite number of suitable river sites that offer the necessary elevation drop and valley structure (topography) for dam construction, and the vast land area required for reservoirs. Solar and wind energy, while having their own challenges, are not constrained by such specific, non-replicable geographical features, allowing for much broader global deployment potential, making B the primary constraint on scalability.

Which renewable energy source is classified as a baseload power provider due to its constant and stable output?

Answer

Baseload power sources provide a constant, stable supply of electricity. Unlike intermittent sources like solar (dependent on sun) and wind (dependent on wind speed), Geothermal power extracts heat from the Earth's interior, providing a consistent energy flow that is not affected by daily or seasonal weather variations, thus classifying it as a dispatchable, baseload source.

Which renewable energy source consistently provides the highest capacity factor?

Answer

Geothermal power plants utilize continuous heat from the Earth's interior, enabling them to operate as a baseload power source with typical capacity factors often exceeding 90%, which is the highest among major renewable energy sources.

Which major renewable fuel is produced through the biological process of fermentation, often utilizing feedstocks like corn, sugarcane, or cellulosic biomass?

Answer

Ethanol, commonly used as a fuel additive, is produced primarily by the fermentation of sugars derived from plant starches or cellulose, a process similar to brewing.

Hydroelectric power plants primarily convert which type of energy, stored in elevated water reservoirs, into electricity?

Answer

Hydroelectric power relies on the gravitational potential energy of water stored at a height. As this water flows downward, its potential energy is converted into kinetic energy, which then drives turbines to generate electricity.
