Organic farming is the form of agriculture that relies on crop rotation, compost, biological pest control, mechanical cultivation, and other techniques using natural processes, to maintain soil productivity and control pests. Organic farming excludes or strictly limits the use of synthetic fertilizers, pesticides, and livestock feed additives. Genetically modified organisms are excluded, and organic standards in Britain and Australia exclude engineered nanoparticles.

"Organic agriculture is a production system that sustains the health of soils, ecosystems and people. It relies on ecological processes, biodiversity and cycles adapted to local conditions, rather than the use of inputs with adverse effects. Organic agriculture combines tradition, innovation and science to benefit the shared environment and promote fair relationships and a good quality of life for all involved..." -- International Federation of Organic Agriculture Movements

Cathy Leslie, Executive Director of Engineers Without Borders-USA
In order to stay competitive, tomorrow's engineer will need to become more culturally savvy, as well as adept at implementing appropriate technologies. Capacity building is not about constructing a showcase engineering project. It's about coming up with practical, sustainable solutions that fit the environment, its people and the culture as well. (ASME)

In physics, energy is an indirectly observed quantity. It is often understood as the ability a physical system has to do work on other physical systems. Since work is defined as a force acting through a distance (a length of space), energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length.

Sustainable energy is the provision of energy that meets the needs of the present without compromising the ability of future generations to meet their needs. Sustainable energy sources are most often regarded as including all renewable energy sources, such as hydroelectricity, solar energy and power, wind power, wave power, geothermal energy and power, biomass fuel and energy, and tidal power. It usually also includes technologies that improve energy efficiency.

While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas, where energy is often crucial in human development. As of 2011, small solar photovoltaic (PV) systems provide electricity to a few million households, and micro-hydro configured into mini-grids serves many more. Over 44 million households use biogas made in household-scale digesters for lighting and/or cooking, and more than 166 million households rely on a new generation of more-efficient biomass cookstoves.
