If I were building a city along the Columbia River, there are several types of energy resources that I would consider using. Here are three types of energy resources that I would prioritize:
Hydroelectric power: The Columbia River is one of the largest hydroelectric power sources in the world, making it an obvious choice for powering the city. Hydroelectric power is clean, renewable, and produces no greenhouse gas emissions. It also provides a stable source of electricity that can be easily controlled and adjusted to meet the city's energy demands.
Solar power: While the Columbia River is a great source of energy, it is not always reliable due to fluctuations in water levels and weather conditions. To supplement this, I would consider using solar power as a secondary energy source. Solar power is also clean and renewable, and can be harnessed using solar panels installed throughout the city. This would provide a reliable source of energy that can help reduce the city's reliance on hydroelectric power.
Geothermal power: The Columbia River is located in an area with high geothermal activity, making it a great source of geothermal energy. Geothermal power is a clean and renewable energy source that harnesses heat from the Earth's core. By tapping into this energy source, the city can reduce its reliance on non-renewable energy sources like fossil fuels, and also reduce its greenhouse gas emissions.
Overall, by using hydroelectric power, solar power, and geothermal power, the city can create a diverse and sustainable energy portfolio that provides a reliable source of energy while minimizing its impact on the environment.
