EEA: Europe has cut emissions by 22.4% since 1990

Total greenhouse gas emissions in the European Union (EU) decreased by 0.4 % in 2016, according to latest official data published today by the European Environment Agency (EEA). Using less coal to produce heat and electricity was enough to make a slight cut in total emissions despite an increase in transport emissions for the third […]

Air conditioning emerges as a key driver of electricity growth

Cooling down is catching on. As incomes rise and populations grow, especially in the world’s hotter regions, the use of air conditioners is becoming increasingly common. In fact, the use of air conditioners and electric fans already accounts for about a fifth of the total electricity in buildings around the world – or 10% of […]

Hydrogen should be used to store excess renewable power, say engineers

While renewable energy sources are providing large quantities of clean power and reducing carbon emissions, they face limitations for the electricity grid when wind and solar aren’t readily available. So far, policymakers have looked to battery technologies are a storate solution. A new report from the UK’s Institution of Mechanical Engineers (IMechE) says greater attention […]

Wave energy set to become a key renewable and reduce emissions 

The wave energy market in Europe stands at potentially £46bn. Research from Marine Power Systems estimates that estimated global wave resources could potentially reach 4,000TWh annually provided the commercial case for the technology improves. Greatest progress on the required technology is being made in the UK. Last August, turbines harnessing tidal energy in the Pentland Firth […]

Skanska:“emissions goals cannot be achieved without tracking embodied carbon”

While it is recognisd that buildings generate more than 170 million tons of construction waste annually; they account for almost 14 percent of all potable water use; and are responsible for almost 40 percent of carbon dioxide emissions, there is a metric missing from our daily conversations: embodied carbon, says Stacy Smedley* of Skanska USA.

Cost of renewables continues to tumble

Over the past year the cost of new solar plants dropped 20%, while onshore wind prices dropped 12%. Since 2010, the prices for lithium-ion batteries — crucial to energy storage — have plummeted a stunning 79% and are projected to keep dropping, according to the latest Bloomberg New Energy Finance (BNEF) report. The economic case for […]

IEA: CO2 emissions on the rise for first time in three years

Greenhouse gas emissions from the global energy industry rose 1.4 per cent in 2017, marking the first rise in three years, according to new data released by the International Energy Agency (IEA). The IEA said the uptick in emissions was fuelled by a 2.1 per cent growth in global energy demand last year – more […]

Smart lampposts could deliver energy savings of between 50-70%. 

European cities spend around €3bn on streetlighting each year, and this figure could be reduced to around €900 million through smart lampposts, An EU smart cities programme is pioneering the delivery of smart lampposts in six cities across Europe, including London, Lisbon and Milan. ‘Sharing Cities’ is aiming to provide an initial 56,000 units in […]

Swedish utility plans major investment in large scale solar generation 

The Swedish state utility Vattenfall plans to invest $100m in large scale solar energy generation over the next two years as it steps up its plans to become fossil fuel free “within a generation”. The SEK1bn investment will go towards developing solar power plants, primarily large scale, throughout 2018 and 2019. The company said it […]

100 cities worldwide now get over 70% of electricity from renewables

Major cities such as Auckland, Nairobi, Seattle and Vancouver now get the majority of their electricity needs from renewables such as hydro, geothermal, solar and wind. The list, compiled by non-profit CDP, is more than double the 42 cities that reported that they were powered by at least 70% clean energy in 2015. With cities […]
