The plan focuses on "Renewable thermal energy has many of the same benefits as other renewable technologies, including improved air quality, economic development and job creation, and the promotion of regional energy security." An industry public described on-site combustion as :responsible for 35 percent of fossil fuel greenhouse gas emissions in New York State. "

STES stores can serve district heating systems, as well as single buildings or complexes. Among seasonal storages used for heating, the design peak annual temperatures generally are in the range of 27 to 80 °C (81 to 180 °F), and the temperature difference occurring in the storage over the

Solar energy has been in use for centuries for heating dwellings and to produce hot water before low cost natural gas was discovered. It gained attention during and after the oil embargo of 1973 as engineers investigated ways to produce thermal energy from a renewable source instead of fossil fuels.

The most popular form of renewable thermal energy is the sun and the solar energy is harvested by solar collectors to heat water, buildings, pools and various processes. Another example of
Renewable Thermal is a Geothermal or ground source Heat Pump (GHP) system, where thermal stored in the ground

September 2015 when it created a new office titled Director of Renewable Thermal. The NY Director of Renewable Thermal will oversee a team to help companies develop and implement renewable, low-carbon cooling and heating systems. NY State considers this
434:(STES), also known as inter-seasonal thermal energy storage, is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season. For example, heat from solar collectors or

from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months. Waste heat from industrial process can similarly be stored and be used much later or the natural cold of winter air can be stored for summertime air conditioning.
