Earth bound radiation losses
The solar resource. Solar energy is the source of all energy on earth, available to us in a number of derivatives. Plant matter for example, which relies on solar energy for nutrition, experiences natural compression and decomposition over millions of years to form the the fossil fuels we use today for electrical generation and transportation. Other examples of this can be seen in use of biomass for fuel or the harvesting of wind energy which is reliant on solar heated air for the formation of currents.

We are also able to utilize the solar resource directly. Solar thermal technologies take advantage of this resource to heat a working fluid that can transfer energy to an air stream or water for domestic or commercial use. Solar Photovoltaic or PV devices exploit various materials (principally Silicon) that experience sub-atomic variations when exposed to solar energy in order to induce an electric current. Both solar PV and thermal technologies provide a useful source of energy with little to no moving parts, no pollution and very little embodied energy.

You can have a green Christmas.
Green living (or sustainable living) is about practical choices, large and small, to preserve the earth and have a better quality of life. It is a lifestyle that attempts to reduce an individual's or society's use of the Earth's natural resources and his or her own resources.

In order to make sustainable choices, it is very helpful to have solid, reliable information that tells us which behaviors are sustainable and which are unsustainable. In quantitative terms, which actions will make the greatest difference, and should be prioritized. Green living can be high tech (buying a hybrid vehicle), low tech (green cleaning, or completely "back to nature." It can be smart grid or off the grid. Sustainable city living explains some of the areas of action for a city dweller.

Practitioners of sustainable living often attempt to reduce their carbon footprint by altering methods of transportation, energy consumption and diet. Proponents of sustainable living aim to conduct their lives in ways that are consistent with sustainability, in natural balance and respectful of humanity's symbiotic relationship with the Earth's natural ecology and cycles. The practice and general philosophy of ecological living is highly interrelated with the overall principles of sustainable development.
