U.S. Government Accountability Office: Science & Tech Spotlight: Renewable Ocean Energy
A Century of Non-Partisan Fact-Based Work: What is it? Renewable ocean energy (or, simply, ocean energy), is energy derived from the ocean's movement, or from its physical and chemical state. In the United States, ocean energy can be generated from waves, tides, and currents, as well as ocean temperature differences. The National Renewable Energy Laboratory estimates that if fully utilized, ocean energy resources in the U.S. could provide the equivalent of over half of the electricity that the country generated in 2019. U.S. government and industry stakeholders predict that ocean energy will likely be first used to provide power for energy and water needs of island and coastal communities and offshore activities. more »
Statement by Canada's Prime Minister Justin Trudeau on National Indigenous History Month
“This month is an opportunity for us to participate in virtual activities to engage with, and deepen our understanding of, Indigenous peoples’ distinct histories, customs, spiritualities, and languages. Doing so is essential to promoting a society based on mutual respect, understanding, and fairness. We all need to play a role in amplifying the voices of Indigenous peoples, dismantling systemic racism, inequalities, and discrimination, and walking the path of reconciliation together. The recent, distressing news of the remains of 215 children found near the former Kamloops Indian Residential School is a painful reminder that the impacts of residential schools are still felt today. Sadly, this heartbreaking discovery in Kamloops is not an exception or isolated incident. Over decades, thousands of Indigenous children were taken from their families and communities, and everything was stolen from them. We must all unreservedly acknowledge this truth and address these historical and ongoing wrongs, so we can build a better future." more »

The Conservancy and the Gardens: Facilitating the Restoration of Samuel Untermyer's Gardens in Yonkers, New York
In 1899 Samuel Untermyer purchased Greystone, the former estate of Samuel Tilden. In the forty one years Untermyer owned Greystone, he transformed the gardens and greenhouses into some of the most celebrated gardens in America. After expanding the estate through property purchases to the north and east of the original estate, he hired Beaux Arts architect Welles Bosworth to design the gardens in 1916. These gardens sprawled over 150 acres overlooking the Hudson River and were maintained by 60 gardeners and supplied by 60 greenhouses. more »
