Green Energy (cont)

Certification schemes to minimise these and similar questionable practices are in place or are being developed in a few countries.

Purchasing green energy through the gas grid

The market for heating is mostly serviced by gas and oil rather than electric power, due to the high cost per kilowatt of electricity in many countries[citation needed]. Distribution of cheap renewable electric power via the electrical grid has made it possible in many countries for the average consumer to choose renewable electric power, and in the same manner bionatural gas may in future be made available to the average consumer via the existing natural gas grid.

Local green energy systems

Those not satisfied with the third-party grid approach to green energy via the power grid can install their own locally-based renewable energy system. Renewable energy electrical systems from solar to wind to even local hydropower in some cases, are some of the many types of renewable energy systems available locally. Additionally, for those interested in heating and cooling their dwelling via renewable energy, geothermal heat pump systems that tap the constant temperature of the earth, which is around 7 to 15 degrees Celsius a few feet underground, are an option and save money over conventional natural gas and petroleum-fueled heat approaches.
