Sustainable development is the organizing principle for meeting human development goals while simultaneously sustaining the ability of natural systems to provide the natural resources and ecosystem services on which the economy and society depend.

Sustainable architecture is architecture that seeks to minimize the negative environmental impact of buildings by efficiency and moderation in the use of materials, energy, development space and the ecosystem at large.

A yearly publication produced by S&P Global recognising companies that are in the top 15% of companies in the sector.

Three closely interrelated pillars: economic, environmental, and social performance.

A process focussed on the future availability of resources that minimise or mitigate the use of harmful sources of energy.

In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation.

A solar balloon is a balloon that gains buoyancy when the air inside is heated by solar radiation, usually with the help of black or dark balloon material.

The solar azimuth angle is the azimuth angle of the Sun's position.

A system of photovoltaic panels is an Array.

Building designs that specifically target the use of solar power.

Solar air heating is a solar thermal technology in which the energy from the sun, insolation, is captured by an absorbing medium and used to heat air.

Solar air conditioning refers to any air conditioning (cooling) system that uses solar power.

A solar air collector consists of an absorber material, sometimes having a selective surface, to capture radiation from the sun and transfers this thermal energy to air via conduction heat transfer.

Soiling is the accumulation of material on light-collecting surfaces in solar power systems.

Soil solarization is a non-chemical environmentally friendly method for controlling pests using solar power to increase the soil temperature to levels at which many soil-borne plant pathogens will be killed or greatly weakened.

Analyst Amory Lovins coined the term soft energy path to describe an alternative future where energy efficiency and appropriate renewable energy sources steadily replace a centralized energy system based on fossil and nuclear fuels.

A sodium-cooled fast reactor is a fast neutron (generation IV) reactor cooled by liquid sodium.

a wind profiler that uses sound waves to measure wind speed at various heights above the ground, and the thermodynamic structure of the lower layer of the atmosphere.

Part of the three sustainability pillars, the pillar that focuses on the support of its employees and other stakeholders of business sustainability plans.

SNOX process is a process which removes sulfur dioxide, nitrogen oxides and particulates from flue gases.
