General Motors Joins the War on Coal

Coal is slowly being ousted by natural gas and renewable energies as an energy source. Even General Motors has joined the fight by eradicating the use of coal from its plants, which will allow the automobile company to prosper in a number of ways, including getting a head start on Obama’s fuel economy mandates. GM and Ford have already moved to aluminum bodies and parts for their vehicles; swapping coal for environmentally friendly energy sources is just another step forward for GM.

What does this mean? GM no longer burns coal in its facilities, instead opting for renewable energies. The company has switched coal out for solar panels, wind power, capture landfill gas (a renewable energy), and steam that has been converted from municipal waste. The technology that GM uses to burn coal, called boilers, are no longer needed and have since been shut down. According to Slate, “General Motors is already 87 percent of the way toward its goal of using 125 megawatts of renewable energy generating capacity by 2020.”

Yet, the corporation still relies on coal: it buys power from electrical facilities that burn coal; only 12 percent of GM’s energy sources are derived from renewables. But we can’t fault the car giant for making investments and efforts toward employing better environmental practices and energy mixes. GM’s small changes will result in bigger leaps to better our environment.

“Sun Powers a Peruvian Energy Shift” – Wall Street Journal, 9 December 2014

Peru President Ollanta Humala has introduced a rural electrification program in his country that embraces renewable energy sources, namely solar power. In Peru’s Cajamarca state, 3,900 homes have been given solar panels, which have drastically bettered these Peruvians’ day-to-day lives. President Humala’s goal is to grant panels to two million people across the Andean highlands and Amazon rain forest by 2018. Additionally, using renewables, like solar power, will reduce carbon dioxide emissions.

But the program is a bold effort; Peru’s landscape can be quite challenging. The rain forest, for instance, has high humidity and heat, which would effect the panels’ performance. Overall, many of the places will be difficult to get to, due to thick jungle and mountainous terrain.

The panels consist of 100-watt systems, an amount that only powers a few lights, a cellphone charger, radio, and TV. That might not be enough for the rural families, who each pay $3.40 a month for the system. Another issue is distrust — many remote communities are suspicious of both foreigners and new technology.

The US might also have a stake in President Humala’s program: if the program is successful, there could be room for US renewable energy companies to invest in Peru. Peru is a great contender for the technology, due to the enormous amount of sunshine it receives and its open-minded government. According to the US Commerce Department, Peru’s renewable energy market could grow to $13 billion by 2020, which encompasses $1.6 billion in solar power.
