The article concerns the performance of a solar water heater with gas backup and an air-source heat-pump water-heater at a dairy farm in Ireland. The publication discusses the heater’s affect on energy efficiency and it’s relation to renewable energy, emission and target interactions as identified in the document.
With more than 600,000 miles of operational transmission lines throughout the U.S., there is a significant opportunity for investments in conservation. By establishing native vegetation in these project corridors, developers and private landowners can add value to the rights of way used by electric transmission infrastructure. The size of prairie strips and the goal of providing conservation outcomes allows landowners and developers to work together to adopt this practice on private farmland within transmission line corridors. Farmers and project developers contemplating the adoption of prairie strips on private lands within transmission line corridors should also note that the width of an individual prairie strip may be adjusted to accomplish the purpose of the practice, prairie strips may not exceed 25 percent of the cropland area per field, developers could form agreements with participating and/or surrounding landowners to manage this vegetation, the Federal Energy Regulatory Commission has vegetative height requirements depending on transmission line voltage and type, and owners of public land may also qualify for cost-share for prairie strips through CRP if the land is being farmed.
The Morris Ridge Solar Project is a proposed solar farm on approximately 1,060 acres in the Town of Mount Morris, southern Livingston County, New York. The project site is within an area farmed primarily in a cash cropping rotation. The Morris Ridge Solar project is being designed to integrate agricultural uses, including a managed grazing system that utilizes sheep grazing to control vegetation growth under and around the solar panels. Sheep grazing is a method of vegetation control used on solar facilities around the world and is increasingly being used in the Northeastern United States to provide a solution that can promote and incorporate an agricultural use within a solar photovoltaic facility. The Morris Ridge Solar project is also being planned to accommodate honeybees and honey production. Through the incorporation of pollinator-friendly vegetation into the project design, solar farms can create suitable habitat for honeybees. Co-locating honeybee apiaries and solar farms has been proven to be a successful method of integrating agricultural use at solar farms throughout North America. The Morris Ridge Solar project will seek to contract the grazing through local farmers who either currently own sheep or wish to expand sheep enterprises as part of their farm business. To engage with these farmers and determine which candidates are best fit for the contracted grazing, MRSEC and AVS have worked to conduct outreach locally and assess interest from the farm community. Initial interest has been solid, with several area farmers expressing interest in contract grazing either parts of the site or the entire site. The solar site will be seeded with a seed mix designed for the special circumstances of the site: grazing, honey production, low-growing, shade and sun tolerant. The seed mix will be selected based on soil testing results, which is scheduled for fall 2020. The seed mix will be something akin to Ernst Conservation Seed’s Fuzz & Buzz Mix. A mix of pasture grasses, legumes (all flowering plants), and forbs (more flowers), it is a diverse and robust blend designed to balance the needs of agrivoltaic production. The seed mix is integral to the vegetation management plan. The vegetation management is planned to support perennial pastures that nearly always have flowering plants. This perennial rotation of the sheep keeps vegetation in sequence of rest and grazing. This sequence is cyclical, and the structure allows the legumes and forbs time to flower from May to October. With the planned rotation of the sheep, the availability of nectar from flowering plants across a large area that are stimulated to bloom consistently throughout the season should allow the bees to thrive. EDF-Renewables has taken care to strategically plan for a high level of agricultural integration at the Morris Ridge Solar Facility. The solar facility is proposed to create a new opportunity for a livestock grazier and a commercial honey producer in the region. Over the rest of 2020, AVS and EDF-Renewables will work to find the right farm partners to facilitate the plans identified above. The construction plans will be fine-tuned with a grazing operation in mind. The future site graziers will have several years to bring their livestock operations up to speed in harmony with the construction schedule. Our team looks forward to project success that incorporates and strengthens the regional agricultural community in the Morris Ridge Solar Project.
Across the U.S., many cities, counties, and states are taking advantage of affordable renewable energy sources, such as solar and wind energy. Over the past nine years, the price of installing solar energy projects has decreased by 70 percent, while the average cost of constructing a wind energy project has fallen by more than 67 percent per kilowatt hour since 1983.1,2 This rapid decline in cost has empowered Americans to embrace affordable, clean, and renewable energy. While all investments in conservation promote environmental improvement, developers can follow a few best practices to ensure project success. For example, native seed mixes offer the greatest return on investment when aiming to provide ecosystem services, such as habitat for pollinators and wildlife, as well as improved water quality and soil health. If possible, project developers should prioritize native seed selections over naturalized, non-invasive species of vegetation. Pollinators play a critical role in the robust food, fuel, and fiber production economy of the Midwest. By pollinating agricultural crops, this group of insects is crucial to ensuring economic and food security. Research shows the populations of all pollinators, including honey bees, native bees, and monarch butterflies, were three-and-a-half times greater on sites with investments in the reestablishment of native vegetation in central Iowa when compared to control sites. Seeding a site with native and naturalized, non-invasive vegetation presents opportunities for the introduction of livestock grazing for management. For example, pollinator-friendly solar sites have seen success with rotational grazing of sheep as a management option. Sheep are recommended for pollinator-friendly solar projects because goats and cattle could cause damage to on-site equipment. Renewable energy sources, such as wind and solar, are growing rapidly. As the industry continues to create hundreds of thousands of jobs, stimulate local and state tax revenue, and reduce greenhouse gas emissions, new investments in electric transmission infrastructure will inevitably occur. By developing resources for site managers of renewable energy infrastructure, public officials at all levels are well positioned to add value to these projects. Investments in native and naturalized, non-invasive vegetation ensure habitat for at-risk pollinators, including the monarch butterfly, while creating habitat for vulnerable wildlife species. These species are crucial for economic and food security in the Midwest and underwriting renewable energy projects with perennial vegetation improves quality of life for all.
