In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton.
Sustainable Energy
Sustainable energy is energy that is consumed at insignificant rates compared to its supply and with manageable collateral effects, especially environmental effects. Another common definition of sustainable energy is an energy system that serves the needs of the present without compromising the ability of future generations to meet their needs. Renewable energy is not a synonym of sustainable energy. While renewable energy is defined as one that is naturally replenished on a human timescale, sustainable (often referred to as 'clean') energy is one the use of which will not compromise the system in which it is adopted to the point of not being fit to provide needs in the future. The organizing principle for sustainability is sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture. Sustainability science is the study of sustainable development and environmental science.
If you take a bale of hay and tie it to the tail of a mule and then strike a match and set the bale of hay on fire, and if you then compare the energy expended shortly thereafter by the mule with the energy expended by yourself in the striking of the match, you will understand the concept of amplification.
William Shockley
We must proceed with our own energy development. Exploitation of domestic petroleum and natural gas potentialities, along with nuclear, solar, geothermal, and non-fossil fuels is vital. We will never again permit any foreign nation to have Uncle Sam over a barrel of oil.

The real key word that triggers my rage is the word "energy". When people start talking about positive or negative types, for instance, negative energy — what are you talking about? What do you mean? Let's think about it, what does energy mean? Well, we know what it means, you know, energy from petrol when it's burned and moves a car and makes it move, it's like this. "This room has positive energy." Now, where the fuck is it going, then? It's not moving. It's covering up such woolly thinking, such pathetic nonsense.
