In this study, cost-effective technological options to stabilize CO2 concentrations at 550, 500, and 450 ppmv are evaluated using a world energy systems model of linear programming with a high regional resolution. This model treats technological change endogenously for wind power, photovoltaics,...

Geological carbon sequestration seems one of the promising options to address, in the near term, the global problem of climate change, since carbon sequestration technologies are in principle available today and their costs are expected to be affordable. Whereas extensive technological and...

Our daily lives are unimaginable without energy. Producing it, however, may be harmful to the environment depending on the energy source. The Paris Agreement brought a key question to the fore: with or without coal? The Powering Past Coal Alliance (PPCA) members, including the European Union,...

This paper establishes a bottom-up LEAP-Kenya-Centralized-Electricity model to simulate the mitigation potential of chief atmospheric pollutants and greenhouse gas (GHG) emissions from 2010-2040 under different scenarios: Business as Usual (BAU), Vision 2030+Least Cost Power Development Plan...

The ambition to reach climate-neutral energy systems requires profound energy transitions. Various scenario studies exist which present different options to reach that goal. In this paper, key strategies for the transition to climate neutrality in Germany are identified through a meta-analysis...

To reliably achieve deep decarbonization of the US power sector, a candidate policy must perform robustly across a range of possible future trajectories of demand, fossil fuel prices, and prices of new wind and solar capacity. Using a modified version of the NREL ReEDS model with scenarios that...
