Sub-national variability of wind power generation in complex terrain and its correlation with large-scale meteorology

Environmental Research Letters, 2020
The future European electricity system will depend heavily on variable renewable generation, including wind power. To plan and operate reliable electricity supply systems, an understanding of wind power variability over a range of spatio-temporal scales ...

Temperature and Farm Labor in Nigeria

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We estimate the impact of temperature shocks on the composition of farm labor in rural Nigeria using a nationally representative household panel survey. Leveraging plausibly exogenous year‐to‐year variation in growing season temperatures, we find that warmer temperatures significantly alter farm labor composition, prompting a substantial shift

Climate Policy : Quo Vadis?

Energy & Environment, 2009
Climate change has become a major issue of our time. While Earth history clearly demonstrates that there has always been climate change, the IPCC (Intergovernmental Panel on Climate Change) keeps reminding us that the current climate change, i.e. the measured recent warming of the Earth, is something exceptional and alarming and is mainly caused by ...

Markets Mitigate Land‐Use Competition From Energy Crops and Increase Farm Revenues

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Meeting the US Sustainable Aviation Fuel Grand Challenge target of 35 billion gal annually by 2050 will require an estimated 380 million–700 million dry tons of agricultural biomass feedstock. This study evaluates the implications of large‐scale biomass production for land use, crop production, and market outcomes under mature market ...

Quantifying the shift of public export finance from fossil fuels to renewable energy

Nature Communications
By providing guarantees and direct lending, public export credit agencies (ECAs) de-risk and thus enable energy projects worldwide. Despite their importance for global greenhouse gas emission pathways, a systematic assessment of ECAs’ role and financing ...

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Utilizing CO2 as a strategy to scale up direct air capture may face fewer short-term barriers than directly storing CO2

Environmental Research Letters
Direct air capture (DAC) is increasingly recognized as a necessary puzzle piece to achieve the Paris climate targets. However, the current high cost and energy intensity of DAC act as a barrier.

Barriers, Risks and Policies for Renewables in the Gulf States

Energies, 2015
The countries of the Gulf Cooperation Council (GCC) have both large fossil fuel resources and vast renewable energy potentials. Here, we investigate in a literature meta-analysis and a survey, whether there is a need for renewables in the GCC, what ...

Eco‐Efficient Processing and Refining Routes for Secondary Raw Materials from Silicon Ingot and Wafer Manufacturing

Advanced Energy and Sustainability Research, EarlyView.
The ICARUS project developed pilot‐scale processes to recover and refine secondary raw materials from silicon photovoltaic (PV) ingot and wafer manufacturing waste. Silicon kerf, graphite, and silica residues are purified into high‐value inputs for the PV value chain and beyond.
