Renewable Energies in one figure. NREL: Energy Systems Integration Home Page

Residential & Commercial At the residential and commercial level, an example of energy systems integration is a combined heat and power system that uses fuel, such as natural gas, to produce heat and electricity simultaneously. Integration also occurs at this scale where systems, such as solar hot water and geothermal pumps, are combined to achieve greater, more efficient power solutions for homes, multifamily units, and commercial buildings. Energy systems at this scale are typically low-voltage (less than 1,000 V) and range from kilowatts to megawatts in size. In most cases, these small-scale systems have a single owner, and they operate under a single set of local rules and regulations. Typically, a small-scale system is located behind a single meter for each type of energy infrastructure (for example, electrical or fuel), but it can communicate demand and generation in...
