REthinking Energy

International Renewable Energy Agency (IRENA), REthinking Energy (2015), 2nd edition: 
"The share of renewables needs to grow not only in power generation but also in transport, heating and cooling. (...) Five clear actions are needed to support the renewable energy transition: Strengthening the policy commitment to renewable energy; Mobilising investment in renewable energy; Building institutional, technical and human capacity; Harnessing the cross-cutting impact of renewables on sustainable development; Enhancing regional engagement and international cooperation."

"(...) the use of biomass (FBR) to energy should be integrated within the framework of policies for the forest sector, through the territorial implementation of forest planning tools, namely the Regional Plans of Forestry Planning and Forest Management Plans, allowing the regional implementation of the national guidelines and the monitoring of sustainable forest management, as well as the coordination with other environmental policies that ensures the different services provided by forest ecosystems."

opinion about energy analysts

"Why do professional energy analysts and agencies have such a tough time getting their arms around wind and solar? Why are they so consistently wrong about renewable energy, in the same direction, over and over again?"

Ecodesign Directive

"Six reasons why building automation should be included in the 2015-2017 working plan"

Heating and Cooling 8 Key Recommendations

"(...) 8 key recommendations were formulated to help guide the European Commission in the implementation of the Heating and Cooling strategy and the upcoming revisions of relevant EU legislation:
  1. Promote the electrification of industry thermal processes to enable demand side response and integrate renewables
  2. Foster residual heat recovery using heat pumps
  3. Improve recognition of building automation as an enabler of energy efficiency in its own right
  4. Promote investment based on the synergies between energy efficiency and demand response
  5. Incentivize package financing to foster investment for building renovation
  6. Devise system level solution(s) through cross-cutting energy legislation
  7. Promote mandatory building efficiency requirements in the Energy Efficiency directive
  8. New Market Design should ensure proper energy pricing" +info

Advanced Energy Materials

Lithium-Sulfur Batteries article number 1501873
"Mansoo Choi and co-workers demonstrate highly efficient transparent conductive oxide (TCO)-free inverted perovskite (CH3NH3PbI3) solar cells by using a graphene transparent electrode. Careful engineering of the interface between the graphene electrode and the hole transport layer enables the highest energy conversion efficiency of 17.1% among TCO-free solar cells to be obtained."

backyard-sized biogas machine

"(...) backyard-sized biogas machine that turns organic kitchen waste, garden waste, and pet droppings into pressurized renewable gas, which can be hooked up to a gas barbeque or burned indoors for heat. (...) Instead of having waste shipped to a central location, the idea is to extract and use energy from organics at the source. (...) capable of generating enough gas to cook three meals daily, assuming ideal conditions where all household organics and pet waste are put into the system." +info

Global wind power capacity tops nuclear energy

"The capacity of wind power generation worldwide reached 432.42 gigawatts (GW) at the end of 2015, up 17 percent from a year earlier and surpassing nuclear energy for the first time, according to data released by global industry bodies. (...) Both wind power and nuclear energy are being touted as alternatives to fossil fuel power as they produce fewer greenhouse gases." +info

heterogeneous catalysts

Hideki Abe, Jia Liu, Katsuhiko Ariga (2016). Catalytic nanoarchitectonics for environmentally compatible energy generation. Materials Today, Volume 19(1), Pages 12-18:
"In this review, we shed light on one of the most versatile energy-conversion technologies: heterogeneous catalysts. We establish the integrity of structural tailoring in heterogeneous catalysts at different scales in the context of an emerging paradigm in materials science: catalytic nanoarchitectonics. Fundamental backgrounds of energy-conversion catalysis are first provided together with a perspective through state-of-the-art energy-conversion catalysis including catalytic exhaust remediation, fuel-cell electrocatalysis and photosynthesis of solar fuels. Finally, the future evolution of catalytic nanoarchitectonics is overviewed: possible combinations of heterogeneous catalysts, organic molecules and even enzymes to realize reaction-selective, highly efficient and long-life energy conversion technologies which will meet the challenge we face."
