Back in 2007, China earned the dubious distinction of overtaking the US as the world leader in greenhouse gas emissions.

Since then, it seemed there would be “no end in sight.” As China’s economy continues to soar, won’t its energy use and GHG emissions follow the same trajectory?

Surprisingly, a new analysis by researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) suggests the answer to that question is a rather emphatic “no.”

According to the research, China’s energy use will level off well before mid-century, even as its population edges past 1.4 billion. Why? Because, somewhere between 2030 and 2035, China will: 1) reach a “saturation” point with regard to consumer goods, and 2) develop alternative energy sources.

For example, the study predicts that before 2050: (more…)

New survey results from CompTIA indicate that businesses today are hungry for eco-friendly technology solutions, and that most firms now make hiring decisions based on IT providers’ green credentials.

More specifically, CompTIA’s Second Annual Green IT Insights and Opportunities study, which was based on an online survey of 650 IT and business executives involved in green initiatives or strategies in the US, UK and Germany, showed that: (more…)

PepsiCo UK and Ireland has released its second environmental sustainability report and announced several ambitious goals aimed at minimizing the company’s environmental impact. It’s obvious that PepsiCo UK recognizes the business impact of sustainability initiatives, and over the next few years, the company will be working towards furthering its commitment to sustainability in significant ways.

For example, PepsiCo UK says it plans to be completely fossil fuel-free by 2023.

As it stands now, one fifth of the company’s electricity is sourced from renewable sources. But PepsiCo UK wants to do even better. According to the report: (more…)

We’ve known for years that smart grid management is important.

A new report shows just how significant updating the grid can be.

As remarkable as it sounds, the report, ‘Battle of the Grids,’ produced by engineering consultancy Energynautics on behalf of Greenpeace, concludes that Europe can convert to almost entirely renewable energy-supplied electricity by 2050 using smart grid management.

More specifically, the report uses extensive computer modeling to show that:

1. Large-scale integration of renewable electricity in the European grid (68 percent by 2030 and a whopping 99.5 percent by 2050) is both technically and economically feasible with a high level of security of supply, even under the most extreme climatic conditions with low wind and low solar radiation.

2. Of course, this type of integration would require significant changes in the energy mix. For instance, in the model presented in the report, by 2030, gas plants provide most of the non-renewable electricity and serve as a flexible backup for wind and solar power. Then, between 2030 and 2050, natural gas as a fuel is phased out, as are 90 percent of the existing coal and nuclear plants.

Last week, US Secretary of the Interior Ken Salazar and Secretary of Energy Steven Chu announced a detailed draft environmental analysis that identifies public lands best-suited for solar development in six western states.

The study, called the Draft Solar Programmatic Environmental Impact Statement (PEIS), was compiled over the past two years as part of the Obama Administration’s efforts to create a framework for developing renewable energy on America’s public lands. More specifically, the Draft Solar PEIS assessed the environmental, social, and economic impacts associated with solar energy development on Bureau of Land Management (BLM) administered areas in Arizona, California, Colorado, Nevada, New Mexico, and Utah.
