Review: Renewable Energy in an Increasingly Uncertain Future

A realizable renewable energy future

The ability of renewable resources to provide all of society's energy needs is shown by using the United States as an example. Various renewable systems are presented, and the issues of energy payback, carbon dioxide abatement, and energy storage are addressed. Pathways for renewable hydrogen generation are shown, and the implementation of hydrogen technologies into the energy infrastructure is...

Discounting an uncertain future

The objective of this paper is to determine the socially optimal discount rate for public investment projects that entail costs and benefits in the very long run. We suppose that there is an exogenous process for the growth of consumption per capita, which is stochastic. We first evaluate the determinants of the discount rate for a specific horizon when the representative agent has a recursive ...

Renewable Energy Provisioning for ICT Services in a Future Internet

As one of the first worldwide initiatives provisioning ICT (Information and Communication Technologies) services entirely based on renewable energy such as solar, wind and hydroelectricity across Canada and around the world, the GreenStar Network (GSN) is developed to dynamically transport user services to be processed in data centers built in proximity to green energy sources, reducing GHG (Gr...
