Scheme of sustainable development: at the confluence of three preoccupations.
Sustainable development has been defined as balancing the fulfillment of human needs with the protection of the natural environment so that these needs can be met not only in the present, but in the indefinite future. The term was used by the Brundtland Commission which coined what has become the most often-quoted definition of sustainable development as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."

The field of sustainable development can be conceptually divided into four general dimensions: social, economic, environmental and institutional. The first three dimensions address key principles of sustainability, while the final dimension addresses key institutional policy and capacity issues.

Worldwide installed capacity and prediction 1997-2010.
Energy development is the ongoing effort to provide sustainable energy resources through knowledge, skills, and constructions. When harnessing energy from primary energy sources and converting them into more convenient secondary energy forms, such as electrical energy and cleaner fuel, both emissions (reducing pollution) and quality (more efficient use) are important.

Increased levels of human comfort generally induce increased dependence on external energy sources. Conversely, comfort can also be realized with lowered energy consumption by the application of energy efficiency and conservation approaches. Wise energy use therefore embodies the idea of balancing human comfort with reasonable energy consumption levels by researching and implementing effective and sustainable energy harvesting and utilization measures.

Use of any given energy source in human societies encounters limits to quantitative expansion. At the beginning of the 21st century some issues have achieved global dimension. Principal fossil energy sources, such as oil and natural gas are approaching production declines that may occur within the span of a generation (see Hubbert peak hypothesis). Closely linked to energy development are concerns about the environmental effects of energy use, such as climate changes. Energy development issues are part of the much debated sustainable development problem.

Selected organization

Kiva partners around the world.
Kiva is a non-profit organization with a mission to connect people through loans for the sake of alleviating global poverty. Leveraging the internet and a worldwide network of microfinance institutions, Kiva lets individuals lend as little as $25 to help fund small businesses run by low-income entrepreneurs around the world.

Loans made on Kiva.org provide 0% interest to lenders. Kiva itself charges no interest from the borrower. Borrowers are charged some interest by the respective microfinance institution handling the individual loan. Kiva.org keeps track of how much interest is charged and will not work with those charging unfair or exorbitant interest rates. Kiva borrowers have a historical repayment rate of 100%. Kiva is working with regulators to allow microfinance institutions to offer variable interest rates to lenders.

Kiva enables microfinance institutions around the world to post profiles of qualified local entrepreneurs online. Lenders consist of any individual with a credit card. Lenders browse and choose an entrepreneur they wish to fund. Kiva aggregates loan capital from individual lenders and transfers it to microfinance partners, called "Field Partners", to disburse and administer. As loan repayments are made by the entrepreneur, the Field Partners remits funds back to Kiva. Once the loan is fully repaid, Kiva lenders can withdraw their principal or re-loan it to another entrepreneur.

Brundtland was Chair of the World Commission on Environment and Development (WCED), widely referred to as the Brundtland Commission, developing the broad political concept of sustainable development and published its report Our Common Future in April 1987. The Brundtland Commission provided the momentum for the 1992 Earth Summit / UNCED and for Agenda 21.

Brundtland was elected Director-General of the World Health Organization in May 1998.
