UNITED NATIONS: Secretary-General Antonio Guterres warned that by 2050 global demand for fresh water is projected to grow by more than 40 per cent and at least a quarter of the world's population will live in countries with a "chronic or recurrent" lack of clean water.

If you want to take a shower or wash dishes in East Porterville, California, you'll probably have to use a bucket. The water stopped running in most houses over a year ago. But nearby, farmers are paying to get rid of around 300 billion gallons of water a year.

As the demand for freshwater and energy increases in San Diego County and Northern Baja, the fresh water supply continues to shrink while energy generation remains heavily dependent on fossil fuels. Due to these opposing trends in supply and demand, it becomes increasingly imperative to identify solutions that move these communities to their preferred state in which they are largely reliant on renewable energy and use water sustainably. Large-scale energy solutions include wind power, one of the must abundant sources of energy in these regions.

There are several different directions that our planet can take to address the ever growing need for water and energy. This will involve integrating technologies of a large and small scale into our grid and into our homes as well. There are two main technologies in which to address large scale water sustainability: desalination and ‘pure water’ recycling. As the California dries out, it is increasingly important to adopt proven strategies to maintain the current standard of living.
