In addition to establishing open space and restoring land, Roseville is making its built environment sustainable. Sustainable development, conserving water, producing renewable energy, increasing energy efficiency, recycling and zero waste, all save money for the city. Waste is non sustainable. The solution is to design waste out of the system and save money through increasing efficiency. Energy efficient building design increases the up front cost of development by 2 percent while increasing energy efficiency by 34 percent. Investment in energy efficiency is repaid after two years. Sustainable construction saves energy and money. Roseville Electric has invested in renewable energy and efficiency. Roseville Electric energy audits on homes boost efficiency. The Roseville shade tree program gives residents free trees to shade their homes. Shade decreases energy bills for air conditioning during the summers. Roseville has a water conservation department. Residents have incentive to do the right thing, as rebates are available from the city to promote water conservation. The city of Roseville has adopted zero waste. Roseville has diverted more than 16,000 tons of green waste into compost and wood chips. Roseville has diverted 64 percent of its waste into recycling and reuse. The city landfill has a life span of 75 years. Anything done to reduce waste increases the life span of the landfill. Cities like Los Angeles, San Francisco, Oakland and Sacramento have stuffed their landfills and are forced to truck their waste out of state at high expense. Zero waste saves money for the city of Roseville and protects the environment. Michael Lee, Roseville.
