As a high school student in drought-stricken Reno, Nevada, Celeste Tinajero initiated significant environmental changes at Reed High School.

In 2011, she secured a $12,000 grant from GREENevada to replace leaky bathroom fixtures with water-saving technology. Following this success, she spearheaded efforts to install a hydration station, raising funds through reusable water bottle sales to cover asbestos removal.

Tinajero graduated in 2013, leaving a lasting impact. Today, she continues her advocacy by designing sustainable living curricula for local schools and researching for Reno's "Bag the Ban" campaign against plastic bags.

Childhood friends Erika and Kayla actively championed river health in their hometown. Through the Youth Tribal Council and a Salmon Run Relay, they raised awareness about the declining Klamath and Trinity rivers. Excessive water diversion for agriculture, requiring dams and heavy irrigation, had severely depleted water tables and fish populations like salmon, sturgeon, and trout.

The Salmon Run Relay, mimicking salmon migration, also educated the community on native diet and culture, featuring a ceremony based on Yurok, Hupa, and Karuk traditions. Erika and Kayla further organized town hall meetings and distributed pamphlets, aiming to unite cultures, promote health, and encourage political engagement for river conservation.

Dr. Shahzeen Attari's research highlights public perceptions of energy consumption, noting a preference for curtailment over efficiency as the primary method for reduction—a view contrary to expert findings.

Her work indicates that the public tends to slightly overestimate energy costs for low-energy behaviors while significantly underestimating them for high-energy behaviors. Attari also identified factors correlating with the accuracy of these predictions.

These findings were presented at the Garrison Institute's Climate, Buildings and Behavior Symposium in May 2010.

Over 1.5 billion people worldwide lack access to electricity, often relying on expensive, hazardous, and polluting kerosene lanterns or candles. The United Nations Millennium Development Goals highlight electrification as crucial for poverty eradication, aiming to electrify 500 million more people by 2015.

Advances in LED technology offer a vital solution. For instance, homemaker Suranjini Kumar transitioned from oil lamps to bright, clean light in her home using D.Light. This demonstrates how modern lighting solutions can improve lives and contribute to global development goals.
