Clean is more than green. Cleantech is new technology and related business models offering competitive returns for investors and customers while providing solutions to global challenges. Ultimately cleantech is driven by market economics therefore offering greater financial upside and sustainability.

In recent times, more and more attention is being paid to finding and developing alternate types of carbon-based fuels besides traditional oil, with an eye to both maximizing efficiency and renewability and reducing harmful chemical by-products.

During the conversion process pathogen levels are reduced and plant nutrients made more readily available, so better crops can be grown while existing resources are conserved.

There are two major methods to purify water: by physical and chemical filtration processes, and by biological processing of harmful substances. Physical and chemical filtration methods, while more costly to implement, provide much purer water than biological processes. Biological methods emply bacteria, and can be further categorized into aerobic and anaerobic digestion methods.

Anaerobic bacteria are often preferred over aerobic bacteria, since providing oxygen to aerobic bacteria, a process called aeration, is often expensive and time-consuming. Many types of anaerobic bacteria also provide the added benefit of producing methane as a by-product of their digestion, which can in turn be captured and used as a source of energy.

At the end of 2006, worldwide capacity of wind-powered generators was 73.9 gigawatts; although it currently produces just over 1% of world-wide electricity use, it accounts for approximately 20% of electricity production in Denmark, 9% in Spain, and 7% in Germany. Globally, wind power generation more than quadrupled between 2000 and 2006.

"Net", in this context, is used in the sense of meaning "what remains after deductions" -- in this case, the deduction of any energy outflows from metered energy inflows. Under net metering, a system owner receives retail credit for at least a portion of the electricity they generate.

This includes businesses that may want to operate in a socially responsible manner, as well as to protect the environment.

Carbon finance explores the financial implications of living in a carbon- constrained world, a world in which emissions of carbon dioxide and other GHG carry a price. Financial risks and opportunities impact corporate balance sheets, and market-based instruments are capable of transferring environmental risk and achieving environmental objectives. Issues regarding climate change and greenhouse gas (GHG) emissions must be addressed as part of strategic management decision-making.
