Apple seems to be embedding its renewable energy commitments into its corporate structure. The company recently created a new wholly-owned subsidiary known as Apple Energy LLC and filed an application to the Federal Energy Regulatory Commission (FERC), which regulates power companies, to be able to sell electricity and other power grid services to non-utility customers. The move is a strong sign that Apple will not only fulfill its plans to operate on 100 percent renewable energy through net-metering, but plans to generate and sell renewable energy back to the grid.

Since Google declared its 100 percent commitment to renewables back in 2012, it has signed contracts that will help add almost 2.6 gigawatts of wind- and solar-generated electricity to the grid by the time all the projects are completely. While each of those installations has its own timetable for completion, at least 900 megawatts of those projects should come online within the next four to six weeks alone, according to one of Google's energy strategy executives. Over the course of next year, all the clean power that Google is adding to the grid will offset what it's using in aggregate. And moving forward, Google wants to ensure that more of the electricity it actually uses can be traced to renewable generating sources.

Ecolab announced plans to offset 100% of its electricity use at Minnesota corporate and research, development, and engineering campuses through a SunEdison program supporting community solar gardens. The program will use shared solar panel sites with grid-connected subscribers to ensure clean electricity is generated for use in the local grid.

Tesla founder Elon Musk has announced a new project that could get millions of people off the grid. Musk's increased interest in the emerging energy storage market has led to plans for a giant lithium-ion battery factory. Home and businesses owners could buy these battery systems for backup power or for managing solar electricity generation and use

As more utilities make reliability and resiliency their twin mantras, none has had more success than Florida Power & Light

The Sierra Club on Monday filed a lawsuit against the US Department of Energy demanding that DOE identify the groups and individuals it consulted with on a soon-to-be released nationwide electric grid reliability study. "We want to make sure that when this study is finally released, that the public and policy makers fully understand how [DOE] went about doing it, who they were influenced by, and whose views they did not take into consideration," said Sierra Club attorney Casey Roberts.

The world's third largest ice cream manufacturer R&R Ice Cream collaborated with Iona Capital and Veolia to convert inedible ice cream waste - the sugar, fat, and protein left behind after cleaning - into biogas that generates power for the UK National Grid. The company uses an anaerobic digestion facility to convert the ice cream waste into biogas.

Cleantech company Nova Innovation has reportedly built the world's first fully operational, commercial, grid-connected array of underwater turbines that generate power from oceanic tides. The array is located northeast of Scotland in the Shetland Islands.

Apple has invested in four subsidiaries of China's largest wind-turbine manufacturer Goldwind, marking its largest clean energy deal to date. The deal will reportedly add 285 MW of clean energy to China's grid across four provinces.

Wind generation in the US has the potential to reach grid parity with natural gas and other energy sources by 2035 without any federal support, according to consulting firm Macquarie Research. "We believe the US is now the most attractive wind market in the world due to the increased visibility of demand in the long term," Macquarie said.

It will take a combination of clean energy expansion, policy change and increased accessibility to take grid 2.0 from concept to reality.

The International Energy Agency (IEA) estimates that more than 1 million electric vehicles (EVs) were on the road in 2015, including 400,000 in the United States. In order to limit global warming to 2°C or less, the agency says the world will need 150 million EVs by 2030 and 1 billion by 2050, implying a 21 percent compound annual growth rate from now until 2050.

A company created by Stanford University is developing a self-sustaining community in the Netherlands. The 25-home neighborhood will produce its own energy from biogas, solar and geothermal sources and will grow its own food. ReGen Villages describes its focus as "[d]esirable, off-grid-capable neighborhoods comprised of power positive homes, renewable energy, water management, and waste-to-resource systems that are based upon on-going resiliency research -- for thriving families and reduced burdens on local and national governments."

China has proposed building a $50 trillion global transmission system that would connect the world's wind farms and renewable energy projects. "Global energy interconnection" would solve global energy instability, climate change and environmental pollution, said State Grid Corp. of China Chairman Liu Zhenya. In such a model, clean energy sources would provide about 80% of the world's total electricity.

The small country of Denmark is making a big commitment to renewables. Today Denmark's electric grid is over 40 percent renewably powered, and the country is aiming to reach 100 percent renewable electricity by 2035 and 100 percent renewable energy in all sectors by 2050. 

China is starting to get serious about tackling pollution and climate issues, and the fate of the rest of the world could depend on how good a job Beijing can do at mapping out a sustainable course for the future. "We need more of everything," says Chinese sustainability leader Peggy Liu. "Wind, solar, a modernized grid. We need to leapfrog over the past and into a clean-energy future."

The U.S. could reduce electricity costs by $7.68 billion per year by installing 54 gigawatts of offshore wind power, according to a study supported by the Department of Energy. The goal of the National Offshore Wind Energy Grid Interconnection Study was "to identify and help address the market barriers to the large-scale introduction of offshore wind energy into the U.S. energy portfolio," according to its authors. The report said offshore wind power could be especially useful in densely populated coastal areas

Electric car manufacturer Tesla has revealed a battery for the home that can store power from solar panels, be used in case of a power outage and potentially transition solar-powered homes to be off the grid entirely. "The goal is complete transformation of the entire energy infrastructure of the world, to completely sustainable zero carbon," said the company's founder, Elon Musk. 

Acciona Agua, the water services division of Acciona, a global renewable energy, infrastructure and water services group, will deploy Spain's first smart water grid in the western city of Cáceres as part of a European project that aims to apply new technologies to the management of drinking water networks.

The Obama administration is aiming to start changing that. Last week, the President - fresh off of announcing a $4 billion renewable energy fund with private investment partners - has unveiled a set of initiatives to bring increased access to solar energy and solar jobs.   The "Increase Solar Access for All Americans" plan involves private sector investment of $520 million and partnerships with Citigroup, GRID Alternatives, SunEdison and half a dozen other companies as well as several states and cities.
