The lower efficiencies mean that it takes years for homeowners and businesses to recoup the money they invest in solar power systems. If the efficiencies were higher, that time for return on investment would be slashed, people would be able to cover more of their power loads with renewable energy and solar power would be much more enticing to people and corporations.

A new report out today shows the cable, satellite and telco service providers — companies such as Comcast, Dish Network and AT&T that bring pay TV into our homes — have begun to really focus on the amount of energy consumed by the almost 200 million set-top boxes installed across America.

A new app that can reportedly cut household energy use by 10% is being rolled out to 200,000 Swedish homes.

A new contender for Britain's greenest home has been unveiled in North Yorkshire.

London Mayor Boris Johnson has launched a tool for public sector organisations to make homes more energy efficient.

It also stated a British household using an average of 10 LED bulbs at home will be able to combat rising energy prices by saving up to £300 off their annual bill.

The scheme allowed householders to make their homes more energy efficient by installing technologies such as solar panels or loft insulation. This was done through loans with no upfront cost which were repaid through energy bills.

As continuous high temperatures and humidity drive up energy use, Mississippi Power is reminding customers that rebates and discounts are available focusing on ways to keep their homes cool and reduce the impact of the hot weather on power bills.

The agreement sets rigorous requirements that will improve the energy efficiency of small network equipment (SNE) by 10 to 20 percent compared to typical, recently-deployed devices and cover more than 90 percent of U.S. broadband households – roughly 80 million homes.

The European Investment Bank (EIB) is funding €325 million (£227.5m) to improve the electricity grid in Spain.

Let's say you just moved into a new home and you've been waiting all spring to finally sit out in your sunroom and look at something other than snow. However, you've noticed lately that it gets really hot and you want to reduce the room's temperature. Here are a few reasons temperatures increase:

Energy Performance Certificates (EPCs) have been in place in the UK since 2008. But have we made maximum use of them in promoting energy efficiency? In the Netherlands they’re taking a radical new approach – by sending every home in the country a document with their A to G home energy rating.

Race Bank, which will be located off the Norfolk coast, will have a capacity of 580MW – enough electricity to power 400,000 UK homes.

The first utility-scale solar power plant in East Africa is now open in Rwanda. Built in the shape of the African continent, the solar farm is expected to generate enough power to supply 15,000 homes and boost Rwanda’s electricity generation capacity by 6%.

The Netherlands is to produce its first commercial tidal energy by placing five turbines between the pillars of the Oosterschelde storm barrier in Zeeland. The tidal turbines will produce enough energy each year to power 1,000 homes, broadcaster Nos says.

In April and May, two earthquakes destroyed large swaths of Nepal leaving 3 million people homeless. As they moved into tents and temporary shelters, the risks of fire and health hazards related to cooking have increased.

The new three-year scheme will target low income homes, carrying out essential repairs and energy saving upgrades.

Small, sleek, and shaped like an egg – the Ecocapsule is the latest in tiny home living from Bratislava-based architectural studio, Nice Architects.

It sounds like something more akin to alchemy, but engineers have developed a new light powered by gravity.

In honor of National Home Improvement Month and just in time for summer, 3M today introduces Ultra Clear Energy Saving Window Film Kits to its line of Home Energy Savings solutions.
