  • Denmark May Hold the Key to Integrating Large Amounts of Intermittent Renewables

    Denmark has consistently maintained a commitment to energy independence since the 1970s when their first policies were put in place. Through collaborations among government actors, grid operators, and utilities, it has built one of the most reliable sustainable energy grids, most notably with 40% of its electricity powered by wind.

  • Trading parking requirements for more mobility choices

    Substitutes for city parking requirements are becoming increasingly popular throughout the United States. Rather than using off-street parking, many housing developers now provide residents with alternatives that promote reduced driving. This method is better for the environment and lowers the cost of housing in urban areas.

  • Taking a conservative approach to clean energy

    As consumers across the country increasingly demand access to cleaner, more affordable energy and traditional coal plants become more expensive to operate, a new group is working to give conservatives a voice in natural gas, wind, and solar energy policies. Though any bi-partisan agreement on climate change has so far seemed impossible to broach, a growing number of Republicans are in agreement about clean energy, and aim to reframe the debate to get conservatives back to the table.

  • How Congress made micro-hydro easier for mountain towns

    Micro-hydro projects in the United States have become much more accessible and more financially viable since Congress passed a law in 2013 making it easier for small hydroelectric projects to get federal approval. Specifically, water treatment plants that can retrofit their systems to generate electricity are an excellent energy opportunity. The plant in Grand Lake now produces more electricity than it consumes.

  • Germany sets a new solar storage record

    Solar power is an important renewable energy in Germany, but when the sun is out, it can overpower the grid. Likewise, when the sun is not out, the reception of solar power decreases. Germany has piloted battery installations that store solar energy for use when the sunlight is not plentiful and has successfully incentivized citizens to use them to lower costs.

  • Company Turns Air Into Fuel In Climate Change Fight

    As CO2 levels continue to rise and increase the precariousness of the state of life as we know it, solutions that are efficient, cost effective, and scalable prove illusive. There may be new hope for one method, especially now with increased public attention on the issue: carbon capture; though previously beyond the financial scope of most corporate and government entities, now scientists are turning captured carbon back into fuel, pulling CO2 from the air, cutting back the need for drilling, and creating a profitable and scalable opportunity to help curb climate change.

  • Green and Cool Roofs Provide Relief for Hot Cities, but Should be Sited Carefully

    Twenty-first century cities face the factors of climate change with intensity as urban heating threatens human and the earth’s health. The University of Notre Dame has conducted research on green and cool roofing projects in the city of Chicago. They have found that green and cool roofs help mitigate the heat in cities; however, these roofs should be installed with other strategies like ponds and trees.

  • The Surprising Success of Micro Hydro

    The Hydropower Empowerment Network takes a country-by-country approach to helping establish micro hydro and other technologies in rural places where electricity is difficult to come by. Micro hydro has even proven to be more durable and sustainable than solar, though solar is cheaper and quicker to install - the reason is the depth of community involvement required. When villagers participate on longer-term, complex projects, they develop pride in their work, learn invaluable new skills, and are empowered to engage with the solution.

  • Researchers work to make milk greener

    Researchers at the University of Minnesota's West Central Research and Outreach Center are looking for ways to make producing dairy milk less energy intensive - something consumers are increasingly demanding. They have had some initial success in increasing efficiency using techniques such as capturing heat from the milk to heat water and experimenting with solar and wind to offset some electricity use.

  • The innovators: the smart systems driving motorists towards smarter cities

    How can traffic efficiency be improved? A Cambridge-based tech firm is pioneering apps that let drivers quickly find available parking spaces (helping save fuel by preventing them from circling the block while they look), alerting local councils when roads are icy, or even increasing the lighting on particular roads when there's an emergency.
