What is the solution of LED Lighting?
LEDs work like solar panels in reverse, converting electrons to photons instead of the other way around. They use 90 percent less energy than incandescent bulbs for the same amount of light, and half as much as compact fluorescents, without toxic mercury. By transferring most of their energy use into creating light—rather than heat, like older technologies—LEDs reduce electricity consumption and air-conditioning loads.
The question about LEDs is not whether they will become the standard in lighting fixtures; it’s when. The price (per watt equivalent) is two to three times higher than incandescents or flourescents, but falling rapidly. Virtually any bulb currently in use can be replaced by LEDs.
Who is Larissa Johnson?
For the last fifteen years, Larissa Johnson has dedicated her life to working with and for communities; helping people create sustainable, walk-able, bike-able, healthy neighborhoods that cultivate and invigorate the communities’ livelihood.
Prior to receiving her MPA in Environmental Science and Policy from Columbia University’s School of International and Public Affairs, she worked predominantly in the field of nutrition, physical activity, and chronic disease prevention and what she gleaned through her work is that the environment is at the center of literally everything we do in life. Without clean air to breathe – how do we stay healthy and combat preventative illnesses? Without clean water – how do we grow nutritious, locally produced food? And without green spaces – how do we learn to play and enjoy the outdoors again the way it was intended?
She is a huge proponent of working smarter, not harder and the only way to accomplish big things with limited funds and limited time is through partnerships. As a leader within the Climate and Energy Savings Movement in Maryland, she hopes to cultivate meaningful relationships that will benefit Marylanders from the mountains to the coast and across political and socioeconomic subgroups.
