MwangaBora solar lamps, created by Evans Wadongo, provide low-cost lighting for villagers, saving their health and money, and helping reduce global emissions from kerosine use.

The ferry will operate in the Baltic Sea between Helsinki, Finland and Tallinn, Estonia and has been designed to comply with the European Emission Control Area (ECA) limits thanks to the use of LNG as fuel.

“Better Buildings Challenge partners are improving their communities by cutting energy waste and reducing greenhouse gas emissions,” said Dr. David Danielson, Assistant Secretary for Energy Efficiency and Renewable Energy.

The UK’s commercial vehicle fleet managers could be missing out on £2.6 billion in fuel costs by not switching to ultra-low emission vans.

Half of all infrastructure firms have no policy to record their energy and emissions use.That’s the stark finding of a survey of 300 major building and manufacturing firms across the globe.

Domestic heating, hot water, lighting, cooking and household appliances account for more than 25% of all energy use in the UK.

In Canada, the Green Mining Initiative successfully installed an automated mine ventilation system in an underground mine in greater Sudbury, Ontario. This resulted to a reduction of up to 40 percent of the energy consumption, reduced greenhouse gas emissions, and cost savings amounting up to $4 million annually.

It is estimated that sustainable lighting could result in initial energy savings of 50-80 percent and lower annual CO2 emissions by 3,000 – 4,000 tons. Retrofitting will be equivalent to savings of $1.2 – $1.7 million per year in energy costs.

According to the Hanoi Energy Conservation Centre (Hanoi ECC), building blocks were one of the central objects to be subject to energy saving measures in the city in 2014. Thanks to the solutions including counselling, support, building blocks in the city have saved 535.3 TOEs and reduced 2,118 tons of CO2 emissions.

These savings would also ensure carbon emission (CO2) reductions of 8.7-17.6 million tonnes a year, according the study, ‘Research to Assess the Barriers and Drivers to Energy Efficiency in Small and Medium Sized Enterprises’.

The Delimara Power Station is currently using heavy fuel oil and running on eight Wärtsilä 46 engines. The project includes the conversion of four of the current engines into Wärtsilä 50SG and four into Wärtsilä 50DF engines.

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

The new energy efficiency standard’s positive environmental impact includes 3.63 quadrillion BTU’s of energy saved during the above mentioned period, that translates in avoiding 265 million metric tons of CO2 emissions equivalent to the annual emissions of about 52 million automobiles.

This could be a classic win-win solution: A system proposed by researchers recycles materials from discarded car batteries -- a potential source of lead pollution -- into new, long-lasting solar panels that provide emissions-free power.

The UK's Department of Energy and Climate Change (DECC) expects renewable energy to increase to meet over 37% of the nation's electricity demand by 2022, in its latest annual energy and emissions projections.

Renewable energy becoming more cost-competitive with fossil fuels isn’t news – as technology improves and more clean power generation comes online, electricity without emissions gets cheaper.

Scientists believe it’s still possible to reduce CO2 emissions by a whopping 50% globally by 2050, but only if countries take drastic measures – like the ones taken by France.

Saving 51.49 TOE (tonnes of oil equivalent) of energy or VND781 million per year, reducing carbon dioxide (CO2) emissions by 185.2 tonnes per year - the Hanoi Daeha Business Center has achieved these impressive energy conservation results thanks to green building development strategies.

Providing auxiliary hydrogen power to docked or anchored ships may soon be added to the list of ways in which hydrogen fuel cells can provide efficient, emissions-free energy.

General Electric Global Research has put together a team of researchers who have accomplished a milestone in the reduction of the price of zero emission buses, by using GE’s new Durathon battery together with a hydrogen fuel cell and a lithium battery.
