Which renewable energy types can be installed on-site or obtained off-site?

1. Coal, oil, and natural gas

2. Hydroelectric, solar, geothermal, wind, and bioenergy

3. Only solar and wind

4. Only hydroelectric

The correct answer is: Hydroelectric, solar, geothermal, wind, and bioenergy

Renewable energy types that can be either installed on-site or obtained off-site include hydroelectric, solar, geothermal, wind, and bioenergy. These energy sources are considered renewable because they are derived from natural processes that are constantly replenished. Solar energy, for instance, can be harnessed through photovoltaic panels installed on buildings or solar farms, either on-site or purchased from off-site providers. Wind energy can similarly be harnessed through the installation of wind turbines; these can be placed on-site or can involve purchasing energy produced elsewhere. Hydroelectric power, while typically associated with large-scale installations in specific locations, can also involve smaller-scale projects that may support local sites. Geothermal energy can be accessed at designated locations or through district energy systems that supply multiple buildings. Bioenergy can be sourced from onsite processes, like anaerobic digestion, or from biogas facilities located off-site. Choices that include coal, oil, and natural gas do not qualify as renewable energy sources, as they are fossil fuels that deplete over time and contribute significantly to greenhouse gas emissions. Options focusing only on solar, wind, or hydroelectric exclude the broader range of available renewable resources recognized in current sustainable practices.
