Fossil fuels remain the obvious cheap way to produce energy and there are significant vested interests in keeping things as they are. Sadly corporate profits lead when it comes to business practices.

Supply side - also known as energy generation technologies.
The supply side of energy efficiency addresses new ways of generating energy and include; nuclear, geothermal, fuel cell, bio gas, solar, wind, wave action, flywheel to name a few. Renewable energy is a class of supply side energy generation, where the "fuel" to create the energy can be considered renewable; sun, wind and water.

Demand side - also know as energy distribution/saving technologies
The demand side of energy efficiency includes anything that can reduce the amount of electricity needed to do the "work" required including; the smart grid, smart meters, power factor correction, energy monitoring solutions, energy efficiency solutions and energy efficient appliances/devices.

Please remember that improving your energy efficiency, be this a supply side or a demand side solution, will require technology, investment and a change in peoples attitude if it is to succeed. In many cases the pay back will be in many years, and the ultimate benefits to generations to come. We encourage you to think longer term and to start somewhere as soon as possible!

Our goal is not to promote any particular solution, but to provide as much accurate information as possible so that you can make an informed decision for your needs.
