Top 10 Performing Countries in Solar Energy

There has always been a desperation to move our dependency from dirty, finite fossil fuels to a more cleaner and sustainable fuel source and since the start of the decade there has been a rapid boom in the adoption of solar energy harnessing. Solar panels are becoming more efficient and continuous developments in the tech mean that…

Can Sun and Wind Make More Salt Water Drinkable?

The oceans have long taunted those who thirst. Records dating to A.D. 200 show that sailors boiled seawater and used sponges to absorb fresh water from the steam. Today, desalination is more sophisticated: multistage flash distillation, reverse osmosis, electrodialysis, and more. But one thing hasn’t changed since the time of the ancient mariners: It takes…

Studies Provide Insight on Two Overlooked Segments of Oil and Gas Industry

Two recently released studies in the journal of Environmental Science and Technology provide new insights into methane emissions from significant sources in the oil and natural gas sector and underscore the urgency of taking action to address pollution from these sources. The studies—focusing on the gathering and processing segment and the transmission and storage segment—were…

Fossil Fuel Subsidies Fall in Gain for Renewables

Countries from Mexico to Germany and Malaysia are increasingly taking advantage of cheap oil by trimming fossil-fuel subsidies, easing the way for renewable power that can help the environment, according to the chief economist of the International Energy Agency. With the global cost of crude cut by more than half, Fatih Birol said the IEA…

Renewables Beat Natural Gas, Provide Half of New US Generating Capacity in 2014

WASHINGTON, D.C. — Ending a year-long race that had been nip-and tuck every month, renewable energy sources cumulatively provided more new electric generating capacity in 2014 than did natural gas. According to the latest “Energy Infrastructure Update” report from the Federal Energy Regulatory Commission’s (FERC) Office of Energy Projects, renewable energy sources (i.e., biomass, geothermal,…

Pinch Analysis

Minimizing energy consumption of processes with Pinch analysis Pinch analysis is a methodology for reducing energy consumption of processes by calculating thermodynamically feasible energy targets (or minimum energy consumption) and achieving them by optimizing heat recovery systems, energy supply methods and process operating conditions. It is also known as “process integration”, “heat integration”, “energy integration”…

Calculating the Future of Solar-Fuel Refineries

In a paper recently published in the journal Energy & Environmental Science, a team led by chemical and biological engineering Professors Christos Maravelias and George Huber outlined a tool to help engineers better gauge the overall yield, efficiency and costs associated with scaling solar-fuel production processes up into large-scale refineries. That’s where the new UW-Madison…

Converting Olive Mash into Cash

An experimental system to create heat and power with waste from olive oil processing is up-and-running in Spain. KTH’s lead researcher on the project, Carina Lagergren, reports on this new way to reduce environmental damage and convert organic waste to energy. Fuel cell technology was the main attraction for the first-ever visit by a U.S.…
