Day 16: June 23rd

We woke up and discussed the San Louis Reservoir. This reservoir uses pump storage rather than a dam. There are two lakes. One lake is at a higher elevation than the other. As water is released from the upper lake into the lower lake, turbines are spun to produce electricity. This is an engineering idea that benefits the environment greatly. This doesn't damage any natural flowing system and is still renewable as water from the lower lake gets pumped back to the upper lake. I feel that this is the way to go when producing hydroeclectricity. I would like to see many dams replaced with this technology, as it can meet peak demands an shows very little impact on the environment. We then headed to San Francisco. I met up with my brother and enjoyed the night life of the city. The city was very clean and nice. The entire class had taken notice of this.
