Renewable power plants need better planning and design
Op-ed submitted by Jared Green
33% of all electricity generation worldwide is from renewable sources. Over the past decade, $3 trillion has been invested in clean power worldwide. In 2018, about two-thirds of new energy capacity installed was renewable. If we are going to keep warming below 1.5 degrees Celsius (2.7 degrees Fahrenheit), the best-case scenario outlined at the Paris Climate Accord, global investment in renewable energy needs to double over the next decade.
The world will need thousands of new solar, wind, and geothermal power plants. In two-thirds of the world, solar and wind are already the cheapest energy option. To reduce coal and oil use, it’s absolutely critical that electricity from renewable sources remain that way. But given the pressures of population growth, climate change, urban sprawl, and resource extraction on our remaining ecosystems, it’s important to also limit the environmental and land-use impacts of the thousands of new facilities expected without delaying the transition to renewable energy.
Given all the constraints, smarter ways to design and build renewable energy projects are needed around the world. Benefits can be achieved by decentralizing renewable energy infrastructure and making it local and equitable. Solar power plants can be built-in or near urban communities to ensure the power generated is accessible and affordable to renters and low-income households and also reduces environmental impacts. Utility-scale renewable power plants can also be planned and designed to reduce impacts on wildlife, and in some instances, even support ecological regeneration. Renewable energy can be designed to serve multiple functions and become real community assets.
A few innovative projects demonstrate how renewable energy could be made much more accessible. In Helsinki, Finland, the 275-kilowatt Suvilahti Solar Power Plant is built atop a power station owned by Helen, Helsinki’s power company. The project is marketed to energy consumers who can’t afford to put PV panels on their roof or who don’t have access because they rent. Through a website, consumers choose their own solar panels at a cost of $5 per month and subscribe in just a few minutes. On average, the energy for a one-bedroom apartment is met through subscribing to five panels, for a total of $25 per month; and their subscription is simply deducted from their energy bill.
For the Coyote Ridge Community Solar Farm in Fort Collins, Colorado, the non-profit energy developer GRID Alternatives partnered with the Poudre Valley Rural Electric Association (PVREA) to build a 1.95-megawatt community solar farm dedicated mostly to serving 140 low-income residents, who see a 30 percent reduction in their annual energy bills. To lower the cost of constructing the facility, GRID Alternatives brought in volunteers and job trainees, who also learn marketable skills in solar power installation.
Wind and solar can be fit into existing ecosystems and even support their regeneration. The 5-megawatt Block Island Wind Farm (pictured right) off the coast of Rhode Island is a model of how to site an offshore wind farm to minimize fatalities among endangered bird species, such as roseate terns and piping plovers, and other environmental impacts on ocean wildlife. The Rhode Island Coastal Resources Management Council (CRMC) assembled experts from academic institutions, including the University of Rhode Island, to undertake a two-year planning effort to map bird paths in an area covering approximately 1,500 square miles. The Ocean Special Area Management Plan, a sort of marine zoning plan for offshore wind, was applauded by President Barack Obama’s Ocean Policy Task Force. The 5-turbine facility demonstrates the value of a comprehensive ecological-planning approach with private and public stakeholders, which should be followed for the 30 additional offshore wind projects now planned along the eastern seaboard.
Across the U.S., beekeepers have partnered with solar power companies like Engie, Enel Green Power, and US Solar Corporation and energy advocates like Fresh Energy to transform sites of solar power facilities into sanctuaries for pollinators. A 2016 global analysis found that 40 percent of pollinator species may be at risk of extinction in the coming years. According to Rob Davis, with Fresh Energy, numerous states, led by Minnesota, have created an ecological statewide standard for vegetation that grows under and around large ground-mounted solar sites and laws, which enables solar power facilities to support increasingly fragile bumblebee, honeybee, and monarch butterfly populations, as well as those of other native bees.
Geothermal and hydropower plants can also support ecological regeneration. Landsvirkjun, Iceland’s national power company, hired a landscape architect to create a new renewable energy design policy, one of the most progressive in the world. After a public backlash over the environmental impact of a hydropower project, Landsvirkjun redesigned its approach to renewable energy infrastructure projects. Geothermal and hydropower projects must now be designed in harmony with the landscape and provide community benefits. Geothermal and hydropower plants in planning stages throughout Iceland show how to marry infrastructure with landscape design, ecological restoration, and placemaking. One planned geothermal power plant even includes a hotel and greenhouse.

US Wind will expand offshore project in Maryland to include up to 82 turbines, company says
Maryland-based offshore developer US Wind announced plans this week to expand its 22-turbine MarWin project to include up to 82 turbines under the new Momentum Wind project for up to 1,200 MW additional offshore wind energy.
US Wind also intends to develop 90 waterfront acres into a new offshore wind deployment hub where the company will invest $77 million through the existing MarWin project. The company will incrementally invest $150 million to develop Sparrows Point Steel – the state’s first manufacturing facility dedicated to creating offshore wind foundations.
“Because of the successes we’ve achieved in the development of MarWin, US Wind is ready to offer Maryland its most ambitious clean energy project to-date and, with it, the state’s first permanent offshore wind steel fabrication facility,” Jeff Grybowski, US Wind CEO, said in a statement. “Developing Momentum Wind and Sparrows Point Steel at full capacity will give Maryland the opportunity to bring steel back to Baltimore and become the epicenter of offshore wind manufacturing.”
The company says the Momentum Wind project could fully meet Maryland’s offshore wind energy goals.
Gov. Larry Hogan called US Wind’s announcement a “game-changing” moment.
“Offshore wind presents a once-in-a-generation opportunity to expand and diversify our economy and our energy portfolio,” he said. “Maryland is proud to continue to be an example of strong environmental leadership, and I am confident that we will be a leader in offshore wind development for decades to come.”
US Wind estimates the Momentum Wind project will generate around 3,600 jobs and more than $1 billion in labor income over 20 years. The company acquired the 80,000-acre federal lease are off the coast of Maryland in 2014. The entire lease area can support approximately 1.5 gigawatts of offshore wind energy capacity.
According to data released earlier this year by the Energy Information Administration (EIA), in both 2019 and 2020, project developers in the United States installed more wind power capacity than any other generating technology.
In its Preliminary Monthly Electric Generator Inventory, annual wind turbine capacity additions in the United States set a record in 2020, totaling 14.2 gigawatts (GW) and surpassing the previous record of 13.2 GW added in 2012. After this record year for wind turbine capacity additions, total wind turbine capacity in the United States is now 118 GW.LINK
