Advocates of Renewable Energy: Be Careful What We Promise
Sixty years ago, nuclear was hyped as a source of energy / electricity that would be “too cheap to meter.” The OPEC oil embargo dashed the western world's dream of bountiful low-cost energy but, when Brian Mulroney was elected a decade later, he terminated Canada's research into renewables because “the energy crisis was over.”That funding cut led to my appointment as head of the Solar Energy ...

Renewable energy progress report
What is the Renewable energy progress report and what is its purpose? The Renewable Energy Directive states that a progress report should be issued every two years. The purpose of this progress report is to assess Member States' progress in the promotion and use of renewable energy in line with the 2020 targets. In addition, it contains sections on thesustainability scheme for biofuels and ...

How do you bring electricity to 620 million people?
Sub-Saharan Africa needs a more reliable energy supply. The way it chooses to meet that need will affect the entire planet. In South Africa, major cities are subject to regular power outages as electric utility Eskom periodically shuts down parts of its distribution system to take the pressure off the aging national grid. Whole areas of Cape Town and Johannesburg are without power for hours at a ...

Partial carbonized nanoporous resin for uptake of lead from aqueous solution
Four partial carbonized nanoporous resins (PCNRs), based on organic xerogel compounds, were synthesised by the sol–gel method from pyrogallol and formaldehyde mixtures in water using picric acid as catalyst. The PCNRs were prepared at different pyrolysis temperatures: T1 = 200 °C (PF-200), T2 = 300 °C (PF-300), T3 = 400 °C (PF-400), or T4 = 500 °C (PF-500). The PCNRs were characterized by ...

Evaluation of thermal steam-explosion key operation factors to optimize biogas production from biological sludge
Thermal steam-explosion is the most extended hydrolysis pretreatment to enhance anaerobic digestion of sludge. Thermal hydrolysis key parameters are temperature (T) and time (t), and the generally accepted values reported from full-scale information are: 150–230 °C and 20–60 min. This study assesses the influence of different temperature–time–flash combinations (110–180 °C, 5–60 min, 1–3 ...

G7 Climate Vision requires Gargantuan Economic Shift
When leaders of the Group of Seven wealthy countries pledge to "decarbonize" the global economy, they're talking about a shift so dramatic that one analyst described it as a new Apollo mission. Like putting a man on the moon, it would require overcoming major hurdles related to technology and money and the political will - so far in short supply - to make it happen. Despite gains by renewable ...

Strategies for recovering inhibition caused by phenolic compounds in a short-cut nitrogen removal reactor treating coal gasification wastewater
Different strategies, including extension of hydraulic retention time (HRT), dilution, and addition of powdered activated carbon (PAC) and super-powdered activated carbon (S-PAC), were investigated for the quick recovery of nitrifying bacteria activity from the inhibition of coal gasification wastewater (CGW). A laboratory-scale short-cut biological nitrogen removal (SBNR) reactor treating ...

European parliament votes to continue requiring ethanol
On May 20, 2015, the European Parliament voted to reject a plan that would eliminate the requirement for import licenses of ethanol of agricultural origin. The plan was rejected with a vote of 486 to 164 amid concerns that the loss of ethanol import data that came from the licenses would negatively impact anti-dumping duty cases. The anti-dumping duties were implemented in February 2013, and are ...
