Rapid depletion of fossil fuels, increasing fossil-fuel price, carbon price, and the quest of low carbon fuel for cleaner environment – these are the reason researchers are looking for alternatives of fossil fuels. Renewable, non-flammable, biodegradable, and non-toxic are some reasons that are making biodiesel as a suitable candidate to replace fossil-fuel in near future. In recent years, in m...

The data presented in this article are related to the research article entitled 'Economic Growth, Fossil Fuel and Non-Fossil Consumption: A Pooled Mean Group Analysis using Proxies for Capital' (J. Asafu-Adjaye, D. Byrne, M. Alvarez, 2016) [1]. This article describes data modified from three publicly available data sources: the World Bank׳s World Development Indicators (http://databank.worldban...

Radiocarbon samples taken over Mexico City and the surrounding region during the MILAGRO field campaign in March 2006 exhibited an unexpected distribution: (1) relatively few samples (23%) were below the North American free tropospheric background value (57±2‰) despite the fossil fuel emissions from one of the world’s most highly polluted environments; and (2) frequent enrichment well above the...

We show, from recent data obtained at specimen North Pacific stations, that the fossil fuel CO2 signal is strongly present in the upper 400 m, and that we may consider areal extrapolations from geochemical surveys to determine the magnitude of ocean fossil fuel CO2 uptake. The debate surrounding this topic is illustrated by contrasting reports which suggest, based upon atmospheric observations ...

A former Republican congressman from South Carolina has started an institution to promote conservative approaches to mitigating climate change and achieving energy security for the United States. According to Bob Inglis, whose Energy and Enterprise Initiative is housed within George Mason University, market distortions lead Americans to use far more fossil fuels than they would if they paid the...

The rate at which the Earth’s surface receives high-utility energy from the Sun is 11,000 times as great as the rate at which humans use commercial energy. Despite this, 88 percent of the commercial energy used comes from non-renewable, fossil-fuel sources. Fossil fuel use each year adds 3 percent more carbon-dioxide to the atmosphere than natural sinks can remove. The task for humans is to fin...

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 barriers and risks presently deter investments, and what possible policy-solutions could be. We find that there is a long-term need for renewables, ...

In order to advance the scientific understanding of carbon exchange with the land surface, build an effective carbon monitoring system, and contribute to quantitatively based U.S. climate change policy interests, fine spatial and temporal quantification of fossil fuel CO(2) emissions, the primary greenhouse gas, is essential. Called the "Hestia Project", this research effort is the first to use...

As a result of declining oil reserves in the world, the rise in fossil fuel prices and growing interest in the environment, there is considerable demand for alternative fuels. Biodiesel is recognized like the "green fuel" and has several advantages compared to diesel. It is safe, renewable, nontoxic, and biodegradable (98% biodegradable in a few weeks). Contains less sulfur compounds, and has a...

The interaction between the Earth’s carbon cycle and climate change remains a top element of uncertainty within climate change projections. In order to better understand this relationship, carbon cycle scientists use a variety of modeling and observational tools to disassemble the many fluxes and reservoirs that constitute the global carbon cycle. In addition to advancing the scientific underst...
