When it comes to being sustainable, it’s important to use renewable energy in terms of specific situations such as air pollution and reducing greenhouse gas emissions in fossil fuels.  For instance, I want to talk about instead of using electrical heaters, the usage of of solar thermal heating.  With solar thermal heating there is a 60% less energy used to heat water, and 35% less energy is used for spaced heating,  so already there is conservation of energy when it comes to renewable energy vs. fossil fuels.  Economically, there is a Lower purchase price when using solar thermal heating systems, and cost less when it comes to reparations and maintenance.  There are two options when it comes to solar collectors.  There are flat plate collectors and evacuated tube collectors, with the only major difference being flat plate collectors using insulation material such as rock wool or polyurethane.  Flat Panel collectors are quite a common purchase in southern climates, while evacuated tube collectors are more useful for winter temperatures where it drops at 40 degrees fahrenheit or lower, with the tubes retaining a high percentage of heat.  Solar heating in general is reliable and flexible, working well with a heat pump or pellet heating.  Overall, if you’re looking for a heating system option that has no CO2 operations when in use, consider replacing  your electrical heating system with solar thermal heating!
