Unfortunately, there is no single silver bullet that will prevent human caused global warming.
Fortunately there are many effective things we can do now to reduce the future impact of our greenhouse gas emissions before they take their toll. We can avoid and postpone emitting them.
In the areas that get lots of sun, solar hot water heating is the most efficient ways of capturing the sun’s energy.
It is most usefull where people tend to use relatively large amounts of hot water during the daytime and in the summer. Although many can benefit financially from solar hot water heating, businesses in the south with good sun exposure are the prime candidates for this technology as they tend to use more hot water in the daytime and in the summer than many homes do. Admittedly most businesses are thinking about their business and not about energy efficiency, this is why a kick start to the industry is helpful.
California
is considering providing tax incentives to homes and businesses that install hot water systems. This is a good thing IMO, although it would be even better if it included free site evaluation to provide a professional opinion considering the cost benefit analysis of each potential individual application considering both the available sun exposure and daily and seasonal water usage. There is no point in installing these where they will not be cost/energy effective.
