It could be stated that by turning off a light you are being energy efficient! However we know in reality this is not the case. Industrial energy efficiency is the cornerstone of any business based sustainability platform. Energy efficiency can include power, combustible fuels, gasses and water.
Making homes, vehicles, and businesses more energy efficient is seen as a largely untapped solution to addressing the problems of pollution, global warming, energy security, and fossil fuel depletion.
How do you move from transactional energy efficiency to transformational energy efficiency? The key is to imbed a business wide focus on energy efficiency which is captured in your business sustainability plan.
The ultimate goal is to save energy, cut costs and reduce pollution!
Trends
Global trends are happening at Country/Government level and at NGO and organisational level.
The International Energy Agency (IEA) is an intergovernmental organisation which acts as energy policy advisor to 28 member countries in their effort to ensure reliable, affordable and clean energy for their citizens
Governments in many countries are increasingly aware of the urgent need to make better use of the world’s energy resources. Improved energy efficiency is often the most economic and readily available means of improving energy security and reducing greenhouse gas emissions. To support better energy efficiency policy-making and evaluation, the International Energy Agency (IEA) is developing in-depth indicators of energy use, efficiency trends and CO2 emissions.
Overall Trends
Between 1990 and 2005 global final energy use increased by 23% while the associated CO2 emissions rose by 25%. Most of the growth in energy use and CO2 emissions occurred in non-OECD countries.
Globally, energy consumption grew most quickly in the transport and service sectors, driven by rising passenger travel and freight transport, and a rapid expansion in the service economy.
Oil products remained the most important final energy commodity with a global share of 37% in 2005, driven by their use in transport. Electricity consumption is growing rapidly in many countries; its global use increased by 54% between 1990 and 2005.
Traditional biomass and coal both remain important in non-OECD countries although their shares of total final energy use are declining.
Energy use has been increasing more slowly than economic activity in most countries. As a result, global energy intensity, calculated in terms of final energy use per unit of gross domestic product (GDP), fell by 26% between 1990 and 2005.
The reductions in energy intensity were largest in non-OECD countries, due to a combination of structural changes and efficiency improvements. In contrast, final energy use per capita increased in most countries between 1990 and 2005. This increase was linked to growing wealth which leads to increased per capita demand for energy-using goods and services.
On average, final energy use per capita in non-OECD countries is only 23% of the level in the OECD.
Better understanding of the factors affecting energy consumption, including the role of energy efficiency, requires indicators based on more detailed data than are available in the IEA statistical balances.
However, this more detailed informationis currently only available on a comparable basis for some IEA countries. Analysis with these disaggregate indicators for 16 IEA countries (IEA16) shows that improved energy efficiency has been the main reason why final energy use has been decoupled from economic growth. Without the energy efficiency improvements that occurred between 1973 and 2005 in 11 of those countries,
Energy use would have been 58%, or 59 EJ, higher in 2005 than it actually was. However, since 1990 the rate of energy efficiency improvement has been much lower than in previous decades.
These findings provide an important policy conclusion — that the changes caused by the oil price shocks in the 1970s and the resulting energy policies did considerably more to control growth in energy demand and reduce CO2 emissions than the energy efficiency and climate policies implemented in the 1990s.
Renewable Energy
Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). In 2006, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, which is mainly used for heating, and 3% from hydroelectricity.
New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 2.4% and are growing very rapidly. The share of renewables in electricity generation is around 18%, with 15% of global electricity coming from hydroelectricity and 3.4% from new renewables.
What practical steps can you take?
Aligned to your GHG emissions inventory the first step is to measure your energy usage. Report your energy usage to your senior management team and then to manage your energy usage by setting a number of goals and initiatives to reduce your energy consumption and to become more energy efficient.
The key focus will be on your M3 strategy – Measure Manage and Mitigate – this is covered in the section on GHG emission inventories.
