Transportation is another sector that has increased its relative share of primary energy use. This sector has serious concerns as it is a significant source of CO2 emissions and other airborne pollutants, and it is almost totally based on oil as its energy source. An important aspect of future changes in transportation depends on what happens to the available oil resources, production and prices. At present, 95% of all energy for transportation comes from oil.

The office copy machines (photocopier) is everywhere. Seven millions unit are in used in the United States and more than 1.5 million are sold each year. Anyone who has worked in an office has probably used at least once or perhaps spend hours making many copies. The copy machines are not cheap, not just the price. Office stencils related equipment is the fastest-growing use of electricity in commercial buildings in the U.S., according to the Department of Energy. The electricity consumed by office equipment companies will cost reaching two million dollar per year and copiers play an important role in this matter. (more…)

Power generation and distribution networks are built with spare capacity to meet peak periods of energy consumption is usually a time when demand for heating and / or cooling is particularly acute accommodate. Normally, peak electricity demand in some cases last just a few hours every year. And while the networks have always had to cope with peaks in recent years, the electricity consumption during peak hours has increased dramatically in the afternoon. (more…)

Imprinted on every batt or blanket of insulation or on every bag of loose insulation is its R-Value. The higher Insulation R-Value, the more insulation value you’re getting, and the more money you’re saving. (Maybe instead of rating insulating material R-3 and R-4 and R-5, it would be more graphic to rate it with dollar signs: $–3, $–4, $–5.) (more…)

Electric and gas utilities’ Research & Development activities deal nearly exclusively with energy conversion, distribution, and energy usage (at least to the extent that these firms still focus on these core businesses). Although detailed data on utility Research & Development are not collected systematically, it seems that Energy R&D spending by many utilities has declined during the past decade or so. For example, a 1996 survey by the U.S. General Accounting Office (GAO) found that the combined Research & Development spending of the 112 largest operating utilities in the United States dropped from $708 million in 1993 to $476 million in 1996.

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…)
