Renewable biomass and biomass derived fuels could readily replace fossil fuels in many of the present energy utilization applications with concomitant environmental benefits. Gasification is a form of biomass energy conversion producing a fuel that could substitute for fossil fuels in high efficiency power generation and CHP applications. While fossil fuel resources are heavily concentrated in ...

[1] Sulfate aerosol from burning fossil fuels not only has strong cooling effects on the Earth’s climate but also imposes substantial costs on human health. To assess the impact of addressing air pollution on climate policy, we incorporate both the climate and health effects of sulfate aerosol into an integrated-assessment model of fossil fuel emission control. Our simulations show that a polic...

This paper studies a dynamic game where each of two large blocs, of fossil fuel importers and exporters respectively, sets either taxes or quotas to exercise power in fossil-fuel markets. The main novel feature is the inclusion of a “fringe” of nonstrategic (emerging and developing) countries which both consume and produce fossil fuels. Cumulated emissions over time from global fossil fuel cons...

[1] Characterizing flow patterns and mixing of fossil fuel-derived CO2 is important for effectively using atmospheric measurements to constrain emissions inventories. Here we used measurements and a model of atmospheric radiocarbon (C) to investigate the distribution and fluxes of atmospheric fossil fuel CO2 across the state of California. We sampled C in annual C3 grasses at 128 sites and used...

The utilization of renewable energies as an alternative for fossil fuels is considerably growing due to an increasing environmental concern and exhaustion of fossil fuels [1-3]. Transportation electrification is one way to replace or reduce fossil fuels with renewable energy sources. Several propulsion systems including hybrid electric vehicles and plug in hybrid electric vehicles have been int...

Mitigating the global warming greenhouse effect while maintaining a fossil fuel economy, requires improving efficiency of utilization of fossil fuels, use of high hydrogen content fossil fuels, decarbonization of fossil fuels, and sequestering of carbon and CO2 applied to all the sectors of the economy, electric power generation, transportation, and industrial, and domestic power and heat gener...

Geoengineering is the intentional large-scale manipulation of the global environment. The term has usually been applied to proposals to manipulate the climate with the primary intention of reducing undesired climatic change caused by human influences. These geoengineering schemes seek to mitigate the effect of fossil-fuel combustion on the climate without abating fossil fuel use; for example, b...

Alternative energy is any energy source that is an alternative to fossil fuel. These alternatives are intended to address concerns about such fossil fuels. Today, because of the variety of energy choices and differing goals of their advocates, defining some energy types as "alternative" is highly controversial. Most of the recent and existing alternative sources of energy are discussed below. K...
