After oil and gas: Meet Alberta workers making the switch to solar

Over 70 Catholic dioceses in the Philippines have entered into an agreement with energy resource company WeGen Laudato Si to install solar panels on their parishes, schools, and other buildings. The Diocese of Maasin on Leyte Island became the first in the world to completely shift to renewable energy. Installing the panels can be expensive, but shifting to solar has saved one diocese at least 100,000 pesos a month in energy bills.

The commercially-based Wind for Prosperity initiative may have devised a solution to meet growing demands for electricity in developing economies, where fossil fuels are expensive, difficult to access, and take a toll on environmental and human health. The venture works to refurbish wind turbines from Europe and re-deploy them in the developing world, providing clean and affordable power where it’s needed most.

Three major US companies are leading the way in developing the technology to extract carbon dioxide from the air: Global Thermostat, Carbon Engineering, and Climeworks. With federal tax credits per ton of carbon dioxide captured and a prosperous system of injecting the CO2 back into the ground to stimulate crop yield, the companies' three different approaches all offer a way to cut into the massive amount of global emissions, an opportunity to make a lot of money with new technology, and a helping hand for states working on achieving new federal guidelines and restrictions for a green future.

An economic shift to renewable energy could take decades, but thanks to rapidly evolving disruptive technologies, dropping prices of solar and wind power sources, and increasing market demand for green business, the new age of renewable energy could encompass the world economy much more quickly.

A new solar array called North Star in the Twin Cities will soon produce enough energy to power more than 20,000 homes. The project allows landowners to evolve beyond a deteriorating farming industry while maintaining native prairie plants under and around the panels for bees and other pollinators. The project is part of the state's 15-year energy plan to reduce carbon emissions by 60 percent and generate a third of its electricity from renewable sources by 2030.

Urban areas contain the highest in concentration of burning fossil fuels, which negatively contributes to climate change. Spearheading the green energy movement, Burlington, VT claims that its city uses 100% renewable energy for electricity. Burlington’s efforts pilot a model for larger U.S. cities to follow.

Two organizations partnered to help eight low-income households convert their homes to become all-electric in Virginia. It entailed replacing fossil-fuel based heating and cooling systems like stoves and water coolers with electric ones. Some of the households saw a reduction in their utility bills. Organizers estimate that over the course of 20 years the changes will result in the households avoiding the emission of over 2 million pounds of carbon dioxide.

The city of River Falls in Wisconsin built the state’s first city-owned solar garden, taking steps to reduce their use of fossil fuels and encourage community members to go green. Now, all city buildings are 100 percent run on renewable energy and residents can sign up for a program allowing them to buy renewable energy. Getting people to take action can be difficult, but city officials say they found the right message to get its residents on board.

Hywind Scotland is the world's first commercial wind farm using floating wind turbines to generate power for about 36,000 homes a year. This approach — which is being seriously looked at by several countries seeking to reduce their carbon emissions and oil-and-gas companies wanting to expand into renewable energy — allows wind farms to work in deeper waters where there is often stronger winds.

Hydrogen fuel has made promising strides from Germany to Japan, thanks to shifting markets for renewables, improved storage technologies, and emissions-reduction goals. Electrolysis that uses renewables to make the fuel could transform transportation and energy infrastructure, but a few concerns about the unintended effects persist.
