It has been observed that Americans are making use of lesser energy overall while making more usage of their renewable energy resources. For decades now, the LLNL (Lawrence Livermore National Laboratory) has been providing innovative solutions for addressing the nation’s environmental challenges. The laboratory develops science as well as engineering technology.
In 2008 and 2009, the United States made use of petroleum and coal in a significantly lesser quantity while making considerable use of wind power. There was also a reported decline in the usage of natural gas while there was an increase in the usage of hydro, solar as well as geothermal power, as per the energy flow charts that were released by the laboratory.
A reduction in the carbon emissions is also imminent. The energy usage in the transportation, industrial, commercial and residential sectors have also declined while nuclear energy usage remained fairly consistent. The ratio of the total energy services to the overall energy usage gives an approximate measure of the nation’s energy efficiency.
