An energy audit is an inspection and analysis of energy use and flows for energy conservation in a structure, process, or system intending to reduce energy input without negatively affecting output. Energy audits can determine specific opportunities for energy conservation and efficiency measures as well as determine cost-effective strategies ...
The water, energy and food security nexus according to the Food And Agriculture Organisation of the United Nations (FAO), means that water security, energy security and food security are very much linked to one another, meaning that the actions in any one particular area often can have effects in one or both of the other areas.

The International Energy Agency projects higher prices of non-renewable energy resources as a result of fossil fuel resources being depleted. It may therefore decrease global food security unless action is taken to 'decouple' fossil fuel energy from food production, with a move towards 'energy-smart' agricultural systems including renewable energy.
All forms of electricity generation have some form of environmental impact, [1] but coal-fired power is the dirtiest. [2] [3] [4] This page is organized by energy source and includes impacts such as water usage, emissions, local pollution, and wildlife displacement.
Managing energy, peak demand and bills in community level may be more feasible and viable, because of the collective purchasing power, the bargaining power, more options in energy efficiency or storage, [24] more flexibility and diversity in generating and consuming energy at different times, e.g. using PV to compensate day time consumption or ...
Different food preservation methods have different impacts on the quality of the food and food systems. Some traditional methods of preserving food have been shown to have a lower energy input and carbon footprint compared to modern methods. [3] [2] Some methods of food preservation are also known to create carcinogens.
Renewable energy sources are essential to sustainable energy, as they generally strengthen energy security and emit far fewer greenhouse gases than fossil fuels. [49] Renewable energy projects sometimes raise significant sustainability concerns, such as risks to biodiversity when areas of high ecological value are converted to bioenergy ...
Energy development is the field of activities focused on obtaining sources of energy from natural resources. [citation needed] These activities include the production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted.
