Energy efficiency

Efficient energy , sometimes simply called energy efficiency, is the goal of efforts to reduce the amount of energy required to provide products and services. For example, insulating a home allows a building to use less heating and cooling energy to achieve and maintain a comfortable temperature. Installing fluorescent lights or natural skylights reduces the amount of energy required to attain the same level of illumination compared with using traditional incandescent light bulbs. Compact fluorescent lights use one-third the energy of incandescent lights and may last 6 to 10 times longer. Improvements in energy efficiency are most often achieved by adopting a more efficient technology or production process.

There are various motivations to improve energy efficiency. Reducing energy use reduces energy costs and may result in a financial cost saving to consumers if the energy savings offset any additional costs of implementing an energy efficient technology. Reducing energy use is also seen as a solution to the problem of reducing emissions. According to the International Energy Agency, improved energy efficiency in buildings, industrial processes and transportation could reduce the world's energy needs in 2050 by one third, and help control global emissions of greenhouse gases.
 

Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy. In many countries energy efficiency is also seen to have a national security benefit because it can be used to reduce the level of energy imports from foreign countries and may slow down the rate at which domestic energy resources are depleted.g

A Do-It-Yourself Guide To Energy Star Home Sealing - ebook
SKU: adiygtes/ebook/000/000

This is a very well done guide to sealing up air leaks in your home. Lots of good how-to pictures. A couple small add-ons I would make: - Replacing older can lights so that you can insulate right over them is a fairly easy DIY job -- it has the advantages of both reducing heat loss to the attic and getting some heat gain from the can light to the room. - The method they give for determining if you have enough insulation is goofy. Instead, use the Insulation Upgrade Calculator or one of the online insulation guides to determine if your insulation is sufficient for your climate.

Can migrogrids make a major contribution to UK energy supply - ebook
SKU: cmmac/ebook/000

Almost all the electricity currently produced in the UK is generated as part of a centralised power system designed around large fossil fuel or nuclear power stations. This power system is robust and reliable but the efficiency of power generation is low, resulting in large quantities of waste heat. The principal aim of this paper is to investigate an alternative concept: the energy production by small scale generators in close proximity to the energy users, integrated into microgrids. Microgrids – de-centralised electricity generation combined with on-site production of heat - bear the promise of substantial environmental benefits. This is brought about by a higher energy efficiency and by facilitating the integration of renewable sources such as photovoltaic arrays or wind turbines. By virtue of a good match between generation and load, microgrids have a low impact on the electricity network, despite a potentially significant level of generation by intermittent energy sources. The paper discusses the technical and economic issues associated with this novel concept, giving an overview of the generator technologies, the current regulatory framework in the UK, and the barriers that have to be overcome if microgrids are to make a major contribution to the UK energy supply. The focus of this study is a microgrid of domestic users powered by small Combined Heat and Power generators and photovoltaics. Focusing on the energy balance between the generation and load, it is found that the optimum combination of the generators in the microgrid - consisting of around 1.4 kWp PV array per household and 45% household ownership of micro-CHP generators - will maintain energy balance on a yearly basis if supplemented by energy storage of 2.7kWh per household. We find that there is no fundamental technological reason why microgrids cannot contribute an appreciable part of the UK energy demand. Indeed, an estimate of cost indicates that the microgrids considered in this study would supply electricity at a cost comparable with the present electricity supply if the current support mechanisms for photovoltaics were maintained. Combining photovoltaics and micro-CHP and a small battery requirement gives a microgrid that is independent of the national electricity network. In the short term, this has particular benefits for remote communities but more wide-ranging possibilities open up in the medium to long term. Microgrids could meet the need to replace current generation nuclear and coal fired power stations, greatly reducing the demand on the transmission and distribution network.

Renewable energy and your historic building
SKU: reyhb/ebook/000

At the mention of renewable energy, usually the first thing we think of is large wind farms or hydroelectric schemes producing enough electricity to serve hundreds, if not thousands, of homes and businesses. But interest is also growing in the use of micro-generation systems serving individual or small groups of buildings. Micro-generation is the production of heat, electricity or both on a small scale from a low carbon source. Many of the technologies use renewable sources, such as solar and wind power, whilst others continue to use fossil fuels, but with greater efficiency than conventional systems. Although many people have already installed micro- generation technologies in their properties, its use is set to become increasingly popular. As a consequence, solar hot-water panels, domestic-sized wind turbines and photovoltaic arrays (PVs) will be a far more common sight in the future.
