The German Government has revealed a new national plan to save more energy for homes and businesses across the country.

The new “energy centre” a building that houses the heating and electricity equipment, will save the Gloucestershire Hospitals NHS Foundation Trust around £10 million over the next 18 years.

There will be up to £30 million in vouchers available to help with the costs of things such as insulation, double glazing, boilers and floor insulation.

Researchers at Cardiff University are looking into new ways of creating a “super grid” that will allow the EU to share the energy it creates.

To give those customers more options for geeking out on energy use, SolarCity has a new app, MySolarCity, which shows real-time home energy usage and offers basic energy assessments, as well as providing social network via which users can share their solar experiences.

Whether it was planting millions of trees, turning food waste into electricity or using smart grid technology to slash its energy use, British supermarket Sainsbury's has been slowly but surely beefing up its sustainability credentials.

“The introduction of solar as the scheme’s first renewable energy product is a fantastic addition to Warm Up North’s range of energy efficiency solutions that will allow even more households to save energy and money.

Every shower, you’ll save enough electricity to power a 60-watt light bulb for eight hours, or a 20-watt LED for 24 hours. Every year, you’ll save the amount of water it takes to wash more than 70 loads of laundry.

The intelligent streetlight system, designed by Dutch Delft University of Technology, using motion sensing technology that automatically dims streetlights to 20% power when no pedestrians or vehicles are in the vicinity—and the idea is ready to go commercial.

The new "L-CSC" supercomputer at the GSI Helmholtz Centre for Heavy Ion Research is ranked as the world's most energy-efficient supercomputer.

Amazon has been under pressure for a while to get its act together when it comes to renewable energy (just last week we wrote about how shopping on Amazon is powered by coal).

According to Lisa Rathke of the Associated Press, energy-saving program Efficiency Vermont has helped ski resorts all over the state make huge strides, with 2,300 new energy-efficient snowmaking guns replacing older wasteful ones.

A mirror that sends heat into the frigid expanse of space has been designed by scientists to replace air-conditioning units that keep buildings cool on Earth.

Most people use more energy this time of year, compared to the rest of the year. There are some ways you can save cash by saving energy.

It converts about 200,000 litres of feedstock and 1,200 tonnes of residues per day. The power generation unit produces enough electricity to supply about 8% of the factory’s total power requirement, which, in turn, saves about £100,000 every year.

According to the EPA, using recycled aluminum only uses 5% of the energy and emissions that are needed to extract new aluminum.

First, British household budgets would benefit from a £5bn saving every year. This means an average annual saving of around £335 for British families.

This researcher has developed a reactor based on conical spouted beds which, by means of flash or rapid pyrolysis, produces fuels and raw materials using various types of waste.

This initiative, according to Benon Mutambi the Electricity Regulatory Authority (ERA) Chief Executive Officer will cost the government about $4.1m. The initial batch will be distributed to consumers starting January 2015.

Keep electric storage heaters on all the time. Our research also found that few people with electric storage heaters fully understand how they work (only 38%). This means that households with electric heating could be paying through the nose by not taking advantage of cheaper night rate electricity.

Big Energy Saving Week – a joint campaign between Citizens Advice, Energy Saving Trust, and the Department of Energy and Climate Change (DECC) – reveals 74 per cent of Brits are still worried about their energy bills.

John Colucci, vice president of sales and marketing at Westchester Modular Homes, says the up-charge is minimal. He claims that a modular home may cost 3 to 5 percent more for a house that is 50 to 60 percent more efficient than the typical home.

With onshore wind costs coming in at about €105 ($133) per MWh, this figure compares favorably to gas (€164/MWh), nuclear (€133) and, most dramatically, coal (€162-233).

Researchers have developed a solar cell that is able to directly split water. It does not produce electricity in a first step and split the water in a second step, but rather only has one step.

Solid-state lighting technologies, which include both LED and organic light emitting diode technologies, have the potential to save Americans $26 billion a year in energy costs by 2030.

The sea has long been a source of Norway's riches, whether from cod, farmed salmon or oil. Now one researcher from the Norwegian University of Science and Technology (NTNU) researcher hopes to add seaweed to this list as he refines a way to produce "biocrude" from common kelp.
