Is Europe tangled in an Energy Dilemma?

-- a _kt75 | reprint Inside Sustainability: Facts, Figures, Bullshit - Part II: Alternative Energy On May 28 the European Commission published its energy security strategy. In the midst of sanctions and strong rhetoric on the need to reduce dependence on Russian gas, this was to be the first salvo in a long term plan to reduce dependence on Russian natural gas. Unsurprisingly, this will not happen any time soon. The ongoing crisis in Ukraine has confirmed two things: Europe continues to be divided on energy security issues , and the importance of energy related matters is modest compared to concern about the right and left wing drift of European politics. That last point only puts energy issues in perspective, which is probably good for many scholars and observers working on the topic, including this author. Energy Security in Europe Reaching European consensus on energy security was rarely successful, despite attempts to develop an overall su

Moneytalks II: World needs $48 trillion in investment to meet its energy needs to 2035

Meeting the world’s growing need for energy will require more than $48 trillion in investment over the period to 2035, according to a special report on investment released today by the International Energy Agency (IEA) as part of the World Energy Outlook series. Today’s annual investment in energy supply of $1.6 trillion needs to rise steadily over the coming decades towards $2 trillion. Annual spending on energy efficiency, measured against a 2012 baseline, needs to rise from $130 billion today to more than $550 billion by 2035. “The reliability and sustainability of our future energy system depends on investment,” said IEA Executive Director Maria van der Hoeven. “But this won’t materialise unless there are credible policy frameworks in place as well as stable a

-- a _kt75 | reprint Download: Quarterly Notes on Sustainable Water Management - Q01/2014 There is a boom in renewable energy sources coming online worldwide, but the predominant types – solar and wind – are problematic due to their variable nature. For most regions of the world, the sun cannot be expected to shine nor the wind blow when required. What is needed is a way to capture that energy when available, perhaps in the middle of the night, when demand is low, and then store it until it can be used when demand rises. But this is not a trivial problem to solve. _progress | M replaces _kt75 | mirror. visit: http://progress-m.blogspot.com . ready: 01.07.2015. close ✕ According to the European Wind Energy Association , at the end of 2013, the UK had 10.5GW of wind turbine capacity installed, with more in planning and construction. As the percentage of energy generated from renewables increases, the intermittency problem becomes more acute, as has been seen i
