Do you mean 1,500 kWh/mo? Generating 15 MWh/mo would be a very large residential system. $150 for 15,000 kWh of electricity saved/returned would only be $0.01/kWh.
Farmers are sunlight harvesters. Figuring out how to turn sunlight + carbon dioxide (renewables) into profitable products for sale can be achieved through good management in addition to appropriate technology.
Soil's water holding capacity can be increased through techniques like green mature and cover cropping. The permaculture approach to water is to slow it, spread it, and sink it.
I am in favor of synthetic meats and other protein sources like bugs. We just need to be mindful of the culture part of agriculture, where animal protein has been a large factor in many people's lives for a very long time.
There are also parts of the world where crop production doesn't make sense due to poor soil, erosion, water, climate, etc. Animal husbandry with good management practices is important and can help improve the functioning of these ecosystems. Now, whether we decide to eat these animals is another question.
Too much water can also be just as devastating as too little water. As our climate warms, more energy will be stored in atmospheric and oceanic waters, creating more powerful hurricanes and storms. On top of that, sea level rise will cause storm surges to be more destructive and costal erosion will gradually sink major costal cities. Climate change is water change.
Making clean water extremely abundant and cheap is also part of the problem. When it's cheap and abundant, instead of valuing it, we tend to waste and pollute it. In many places, we're not paying the true cost of clean water. In other places, some bioregions just can't support as many people as it does today without expensive technology and its unintended consequences. It's not technology that needs to change; it's our worldview about our relationship with water.
