Did You Know?
Lighting, Heating and Air Conditioning account for up to 70% of energy usage in most commercial buildings.

From lighting and heating to water conservation, weatherization and controls, Lime Energy’s has the in- house technical expertise to identify and implement energy efficiency programs that drive long term business value. Saving energy through efficiency not only contributes to grid reliability and sustainable communities, but it also increases overall profitability by putting money back onto the bottom line month after month.
Why is energy efficiency important?
Energy efficiency produces the cleanest and most abundant untapped energy resource in the country. There is no better way to reduce our dependence on fossil fuels and reduce pollution and greenhouse gas emissions than to improve the efficiency of our energy usage. Energy efficiency solutions allow us to continue to use the energy we need, but in a more efficient and lower-cost way. Not only do we save money now, but we can create a sustainable environment for future generations.
3 Key Reasons for Participating in Energy Efficiency Programs:
- Reducing near and long-term operations costs for businesses
- Low risk, high return utility and government incentives
- Meeting the massive energy needs of the developing world while reducing the world’s usage of fossil fuel and lowering pollution and greenhouse gas emissions
