Salt water and sediment could damage ocean-bound machines waves can crash with incredibly strong force and deploying or servicing devices offshore can be costly-in terms of time and money. Marine energy can be a challenging resource to harness. Why Hasn’t Marine Energy Progressed as far as Solar, Wind, and Hydropower? This flexible delivery of energy could provide power to remote, coastal, and island areas and help make communities more resilient to crises, including the effects of climate change. Plus, if bad weather or natural disasters disrupt electricity and water supplies, marine energy systems can potentially kick in to help provide both. When the sun sets and winds slow, oceans and rivers keep powering on, filling any energy gaps. By collecting as much data as possible on interactions, noise, and other potential changes to natural environmental conditions, WPTO is ensuring that environmental safety is a top priority for the marine energy industry.Ībundant, predictable, and clean marine energy could serve as a valuable complement to other renewable energy resources. For example, the Triton Initiative, led by Pacific Northwest National Laboratory, tested underwater acoustic camera technology to evaluate fish interactions around deployed marine energy devices in Alaska and New Hampshire. Department of Energy’s Water Power Technologies Office (WPTO) is funding research to learn how to responsibly deploy marine energy devices so they can coexist with wildlife and their ecosystems. What is the Marine Energy Industry Doing to Protect the Environment? In the longer term, marine energy can also play a big role in decarbonizing the country’s power grid. These technologies could help observe the ocean to predict destructive storms (like nor’easters and hurricanes), measure ocean health, provide clean water in disaster relief scenarios, and power food- and water-production systems. Marine energy technologies can also power offshore work and the blue economy. For example, Eastport, Maine, comprises scattered island communities, which could get power from the Atlantic Ocean’s immense tidal energy rushing past their shores. coastal communities and provide local, affordable, and clean power to rural and remote island communities, which often rely on expensive shipments of fossil fuels. In the short term, marine energy could serve U.S. coastal communities have abundant marine energy resources flowing nearby. ![]() ![]() Alaska could soon be a marine energy powerhouse, and many U.S. The inlet is capable of providing enough energy to power 7.5 million homes. Alaska’s Cook Inlet possesses one of the greatest tidal energy resources on Earth with currents that can stream in and out at 9 miles per hour. ![]() Some locations carry huge amounts of potential power. Even if only a small portion of this technical resource potential is captured, marine energy technologies would make significant contributions to U.S. The total available marine energy resource in the United States is equivalent to approximately 57% of all U.S. The opportunities to harness marine energy are abundant. How Much Power Could Marine Energy Generate?
