How to Build the Supergrid
Check out the latest Scientific American article on how to build the supergrid (paid article).
Smart grids could save Europe €52bn
Experts from the Smart Energy Demand Coalition state that smart grids and smart meters could save Europe €52bn.
Smart grids reduce losses in the electricity network through automation and smart meters provide information on energy consumption to consumers and allow them to manage their consumption.

Smart grids reduce losses in the electricity network through automation and smart meters provide information on energy consumption to consumers and allow them to manage their consumption.
Utilities will also be able to lower the system voltage level and make meter-reading redundant, argued Chris King, chief regulatory officer at eMeter. After deducting necessary costs like the installation of smart meters and new software, the net benefit would still be €31 billion per year, he said.

Energy efficiency and emissions reduction
According to the EPA, energy efficiency is most likely the most cost effective way for industrial facilities to reduce greenhouse gas emissions.
The revised Clean Air Act states that from January 2011, new facilities or major modifications to existing ones should employ the best available control technology (BACT) to minimise emissions

Roadmap 2050
Roadmap 2050 is an initiative by the European Climate Foundation to provide a practical, independent and objective analysis of pathways to achieve a low-carbon economy in Europe, in line with the energy security, environmental and economic goals of the European Union.
In 2050 is it technically possible and affordable to have an electric mix of 80% renewable energy, 10% fossil fuels with CCS and 10% nuclear. For this to happen, governments need to start cooperating now to create an European "super grid" reliable for high shares of renewable energy supply and to define ambitious targets to 2020 for greenhouse gas emissions reductions, so that the carbon price starts working as a stimulus for innovation and competitiveness.
Reports are available for download here.

World Energy Outlook 2010
World Energy Outlook 2010
The world appears to be emerging from the worst economic crisis in decades. Many countries have made pledges under the Copenhagen Accord to reduce greenhouse-gas emissions. Commitments have also been made by the G-20 and APEC leaders to phase out inefficient fossil-fuel subsidies. Are we, at last, on the path to a secure, reliable and environmentally sustainable energy system?
What more must be done and spent to achieve the goal of limiting the global temperature increase to two degrees Celsius? What would be the impact of these actions on oil markets?
How will emerging economies increasingly shape the global energy landscape? Where will their policy decisions lead us? And will China sustain and intensify the four-fold improvement in energy intensity it has achieved in the last thirty years?
How quickly will the contribution of renewables to meeting the world's energy needs grow? How much will it cost? And to what extent does growth in deployment and use of renewable energy hinge on government support?
All these questions and many others are answered in the World Energy Outlook 2010 (WEO-2010).

Article uploaded in Pluridoc
Analysing the implementation of three vehicle renewal and one urban mobility measures defined in the Portuguese Energy Efficiency Action Plan (PNAEE) is available in Pluridoc.
Abstract:
The Portuguese Action Plan on Energy Efficiency (PNAEE) aims a 10% reduction in final energy consumption in 2015, compared with the average of final energy consumption from 2001 to 2005, through the implementation of energy efficiency policies in transportation, residential, services, industry and government. The transportation sector is responsible for more than a third of final energy consumption and will have the highest predicted energy savings (41%). This paper analyses the implementation of measures included in the vehicle renewal and urban mobility programs. The vehicle renewal program aims to increase energy efficiency of cars through incentives to replace them by more efficient ones and equipment changes. It focuses on reducing the percentage of passenger and commercial vehicles with more than 10 years to 30% and the greenhouse gas emissions from new cars to 110 g CO2/km, so low emissions vehicles represent 10% of the total number of cars circulating in 2015. Urban mobility program aims to encourage the use of public instead of individual transport in urban areas through the creation of mobility plans, the increase in efficiency of public transportation and modal shifting in cities. It focuses on transferring 5% of passenger km (pkm) in Metropolitan Areas of Lisbon (AML) and Porto (AMP) from individual to public transportation in 2015. Based on estimated car ownership, end-of-life vehicles’ decommissioning and new low-emission vehicles sales, the paper concludes that meeting the targets for vehicle renewal measures is unlikely. Based on the increase from individual transport in pkm in AML and AMP, meeting the target is likely. However, trends in pkm are uncertain in the upcoming years. Even assuming that public transportation will continue losing pkm (from 1991 to 2001, the transportation system in AML and AMP changed from one based on public transport to one based on individual transportation), the percentage loss to cars remains difficult to estimate.

Interview with Tulsi Tanti (in portuguese)
An interesting interview with Tulsi Tanti, the CEO of Suzlon (Indian wind turbines manufacturer) can be found here (in Portuguese).
Suzlon is the third largest manufacturer of wind turbines in the World.
Tanti argues that tariffs should be dynamic and that who should pay renewable energies costs' is everyone that consumes above the average and in the peek hours.
