A key tool in resource efficiency is measuring different aspects of resource use (e.g. carbon footprint, water footprint, land footprint or material use), then identifying 'hot spots' where the most resources are used or where there are the best opportunities to reduce this resource use. For example, WRAP has published information on hotspots ...
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. [2]
[1] [2] Water efficiency differs from water conservation in that it focuses on reducing waste, not restricting use. [3] Solutions for water efficiency not only focus on reducing the amount of potable water used but also on reducing the use of non-potable water where appropriate (e.g. flushing toilet, watering landscape, etc.).

This is a list of free and open-source software packages (), computer software licensed under free software licenses and open-source licenses.Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open-source.

These are then met through a set of technologies which draw on a set of resources, both characterized by their potentials and costs. These resources are not limited to energy commodities and may include, for example, water and land-use. This enables OSeMOSYS to be applied in domains other than energy, such as water systems.
LEMON is an open source graph library written in the C++ language providing implementations of common data structures and algorithms with focus on combinatorial optimization tasks connected mainly with graphs and networks. The library is part of the COIN-OR project. LEMON is an abbreviation of Library for Efficient Modeling and Optimization in ...
Current energy-efficient refrigerators, for example, use 40 percent less energy than conventional models did in 2001. Following this, if all households in Europe changed their more than ten-year-old appliances into new ones, 20 billion kWh of electricity would be saved annually, hence reducing CO 2 emissions by almost 18 billion kg.

[5] [better source needed] Energy efficiency implementation may need to be tailored to one's environmental needs. [6] For instance, Christiann Abeelen's research on the energy efficiency projects in the Netherlands showed "Our findings show that large differences exist in the realized savings between individual companies.
