Do we have the resources? Rudolf Diesel developed the diesel engine which ran on biodiesel vegetable oil in the late 1800s. At the time, he speculated that his discovery seemed insignificant, but later could prove to be as important as mankind’s uncovering of future energy uses for petroleum and coal tar. Given the U.S.’ rapid expansion into biofuels, it would appear his vision was correct due to the drawbacks of biofuels. But widespread adoption of biomass-based fuels is not a foregone conclusion. Two questions haunt its progress. First, will it truly reduce U.S. reliance on fossil fuels? And second, is there enough farmland to accommodate widespread production, without jeopardizing food supplies? (more…)

Although the automotive industry is a vigorous sponsor of research and development in vehicle efficiency technology—worldwide, nearly $20 billion U.S. worth in 1997—governments throughout the world sponsor additional automotive R&D, both separately from and in partnership with the industry. This work focuses primarily on four areas: emissions reduction, safety, fuels, and fuel economy. Within the past few years, government sponsorship of automotive R&D has moved sharply in the direction of attempting to advance the performance and cost-effectiveness of automotive fuel cells vehicles, which address three of the four areas: emissions, fuels, and fuel economy.

For processes that produce multiple products, energy and emission burdens have to be allocated to individual products. ISO 14040 advocates reducing the need to allocate by expanding the system boundary. That is, when comparing two systems, the system boundaries for both can be expanded so that all products from both systems are within a newly expanded single system. In transportation FCAs, the system boundary expansion is also called the displacement method. (more…)

The broad range of home solar energy systems are mostly known as Photovoltaic Systems (PV) or Thin Film Solar Technology. The system applies solar panels to create electricity for use in individual homes and cross-feeding in a electric grids with electricity to give supply to other city or municipality. Several countries around the world have realized the enormous potential of solar energy supply and place the necessary systems are able to make this a very successful energy alternative. (more…)

Although the focus of many policy studies of climate change is on establishing the causal links between anthropogenic systems, emissions of greenhouse gases climate change, the line of causation also runs the other way. Short-term fluctuations in climate conditions, particularly in the temperate zones on the planet, affect energy consumption. If the popular expectation that the climate will become warmer becomes a reality, we can expect winters and summers that are warmer than those of the past. (more…)
