US edges closer to energy independence

Science Focus

original post »

The net energy consumption of the US has held fairly steady for nearly 20 years. Over the past decade, however, there's been a large increase in production of energy within the US. As a result, the US government's energy figures for the first half of this year show that the differences between production and consumption have dropped to the lowest level in 29 years. This represents a net drop in energy imports by 17 percent compared to the same period a year earlier.

According to the Energy Information Agency, the boost in energy production came from a variety of sources. Natural gas was the largest, accounting for just over half of the annual increase. Coal accounted for another quarter, renewable energy for 12 percent, and petroleum for eight. The EIA also notes that energy use this year was unusually high due to the intense cold that hit most of the nation in the first few months of 2014.

The vast majority of the country's imports come in the form of petroleum products and crude oil. These imports have been decreasing as new sources of oil are tapped and automotive efficiency standards are tightening. Refined petroleum products remain the largest US energy export; smaller quantities of coal and natural gas are also shipped overseas.
