Final answer:
Biodiesel (B) and Hydropower (E) are renewable energy sources replenished through natural processes, whereas Oil (C) and Coal (D) are non-renewable fossil fuels.
Step-by-step explanation:
Renewable energy sources are those that can be replenished naturally over the course of human lifetimes. These include sources like hydropower, wind power, solar power, and biomass energy. Non-renewable energy sources are those that deplete over time and cannot be quickly replenished; examples include fossil fuels such as oil and coal. From the options provided, Biodiesel (B) and Hydropower (E) are renewable energy sources. Biodiesel is a form of biomass energy, which is derived from plant material, and hydropower uses the movement of water to generate electricity. Both are continually replenished through natural processes like the hydrologic cycle and organic growth, and both are ultimately powered by the sun's energy. This contrasts with options such as Oil (C) and Coal (D), which are non-renewable fossil fuels that require millions of years to form.
