CLOSING THE FLOODGATES: HOW THE COAL INDUSTRY IS POISONING OUR WATER AND HOW WE CAN STOP IT
Coal-fired power plants are identified as the largest source of toxic water pollution in the United States, discharging billions of pounds of heavy metals into waterways annually. A review of 386 plants reveals that nearly 70% of those discharging coal ash and scrubber wastewater have no effluent limits on key toxins like arsenic and mercury, often operating under expired permits. The report highlights severe ecological damage, including massive fish kills in North Carolina and groundwater contamination in Missouri and Illinois, and notes that these plants are frequently located in marginalized communities. While the EPA proposed updated standards, the report argues that political interference from the Office of Management and Budget (OMB) weakened these options. It advocates for 'Option 5,' a zero-discharge standard utilizing dry ash handling and vapor compression evaporation, asserting that such controls are cost-effective and would significantly reduce pollution.

Nebraska’s Path to an Energy-Efficient Future
The document outlines the economic and environmental benefits of energy efficiency in Nebraska, asserting that such policies can help the state meet approximately 50% of its carbon pollution reduction goals under the EPA's Clean Power Plan. It projects that by 2030, a combination of 1% annual energy savings, national model building codes, and 40 MWs of new combined heat and power could avoid over 4 million tons of CO2 and save Nebraskans more than $382 million.

MEETING GROWING ELECTRICITY DEMAND WITHOUT GAS
The document addresses the recent surge in U.S. electricity demand driven by data centers, manufacturing, and electric vehicles. It warns that utilities are defaulting to new gas plants, which risks creating stranded assets and conflicting with climate goals. The authors propose a portfolio of alternatives, including aggressive energy efficiency, the reuse of fossil fuel interconnection sites for renewables, demand response with large customers, and grid-enhancing technologies to improve existing transmission infrastructure.

CASE STUDY: Transition to Clean Energy for Cooperative Utilities
The document details Tri-State's Responsible Energy Plan (REP), announced in January 2020, which aims to retire significant coal capacity and add over 1 GW of wind and solar power by 2024. It outlines the economic and policy drivers behind the shift, the use of a multi-stakeholder advisory group to build credibility, and the challenges associated with stranded assets, transmission development, and the lack of a regional transmission organization in the West. The plan targets a 100% clean energy portfolio for Colorado by 2040 and a 70% reduction in emissions from Colorado wholesale electric sales by 2030.

Scientists Call for Canceling New Land Based Nuclear Missiles
The document argues that the Sentinel ICBM program is prohibitively expensive, increases the risk of nuclear war due to high-alert postures, and is unnecessary given the existing submarine-launched ballistic missile capability.

Microsoft Word - greatplains.doc
The Great Plains region has experienced increasing average temperatures and shifting precipitation patterns, with winter temperatures in northern states rising by more than 6°F over the last 30 years. Climate change is projected to exacerbate the depletion of the High Plains (Ogallala) aquifer, particularly in the southern region where unsustainable water use and extreme heat are already prevalent. Agriculture and livestock are highly vulnerable; rising temperatures are expected to shift crop zones, increase pest prevalence, and reduce livestock yields, with a projected 10% decline in cow/calf and dairy operations under higher emissions scenarios. Ecosystems, specifically prairie potholes and playa lakes, face threats from altered evaporation and recharge rates, which impacts migratory birds and aquifer replenishment. The document also highlights the vulnerability of 65 Native American tribes on rural lands facing water quantity and quality issues.

Assessing Wind Resources
The document outlines a 'funnel' process for wind resource assessment, moving from general wind maps to site-specific measurements. It emphasizes that wind energy production is approximately proportional to the square of wind speed, meaning small estimation errors can lead to significant financial losses. The guide details the use of wind power classes, the impact of wind shear on tower height selection, and the importance of analyzing year-to-year wind variability to satisfy lender requirements. It also provides specific siting advice regarding wind roses, turbine wake effects, and the use of set-backs or easements to protect wind access.

Koleen Haldeman
Koleen Haldeman used a scholarship grant to visit Churchill, Canada, and subsequently integrated her observations of polar bears and Arctic ecosystems into various science courses in Nebraska. By combining personal accounts with WWF resources, she taught students about genetic adaptation, the biomagnification of toxins, and community-based coexistence strategies, aiming to make climate change and conservation feel immediate and relevant to students in the Midwest.

SUSTAINABLE GROUNDWATER MANAGEMENT FOR AGRICULTURE
The report highlights that over one-quarter of global irrigated food production relies on unsustainable groundwater extraction, leading to land subsidence, saltwater intrusion, and ecological damage. It proposes four key strategies for sustainable management: measuring and managing data, setting sustainable extraction limits, enhancing recharge through managed and nature-based solutions, and reducing demand through crop shifting or fallowing. The authors emphasize that strong water governance and local partnerships are essential to implement these technical solutions effectively.
