Energy

Energy refers to the electricity and natural gas delivered to the Columbia community. Emissions associated with energy use account for 70% of Columbia’s total greenhouse gas emissions. Reducing that consumption and increasing the renewable energy goals voters approved in 2004 present great opportunities to both reduce greenhouse gas emissions (GHGs) and enhance our resilience.


The CAAP process identified these two energy sector goals:


    1. Increase generation and use of renewable energy sources, including on-site solar and energy storage.
    2. Improve energy resilience and demand management.

Energy Use

Community Energy Use

Energy is a critical resource that we rely on to go about our daily activities, especially for heating and cooling our homes. By burning these fuels, we are contributing to climate change and polluting our air and water resources. Through continuing to increase our use of renewable energy and improving the efficiency of our homes and businesses, Columbia can reduce its overall community energy use, reduce GHG emissions and become more sustainable. The majority of our energy use and related emissions come from electricity produced by coal and natural gas fired power plants. A much smaller portion of these emissions come from the use of natural gas for water and space heating. Clean, carbon neutral energy sources of electricity for Columbia are critical to meeting the CAAP’s Energy Sector goals.

UNIT
Energy from different sources is measured in different ways—electricity is measured in kWh, natural gas in therms, oil in gallons. We can convert these different measures into a common measure—million British Thermal Units (MMBTU)—to better understand and compare total energy use.

Energy Use By Sector

In 2015, 43% of Columbia's natural gas and electricity consumption was used in our homes. Our commercial businesses used 40% and industry used 17%. Download the data for this chart

   

Energy Use

Municipal Energy Use

Municipal energy use measures the energy used to power, heat and cool City-owned facilities, light the streets, and treat and pump water and wastewater. Columbia has a goal to reduce GHG emissions associated with City operations by 50% below 2015 baseline by 2035 and 100% by 2050. Improving energy efficiency of our buildings and increasing on-site renewable energy actions are ways we can meet these goals.

Renewable Energy

Clean Energy For All

Renewable energy sources are those which naturally replenish in a short time. The most common are solar and wind. Using these “clean” energy resources, as opposed to coal and oil, does not result in an increase in GHGs in the atmosphere. Columbia has already taken several steps toward meeting its energy goals, including adopting a Renewable Energy Ordinance that requires an increasing percentage of electricity to be generated with renewable sources.

UNIT
We track renewable energy by measuring the percent of electricity used that is supplied by renewable energy resources vs. fossil fuel-based sources.

Renewable Energy

Columbia is committed to increasing the percentage of its electricity supplied from renewable energy sources. In 2018, nearly 16% of our electricity came from wind, landfill methane and solar. The current ordinance goal is 30% renewable electricity by 2028. The CAAP calls to increase this goal to 100% by 2035.

Columbia’s Renewable Energy Sources

In 2017, Columbia supplied nearly 16% of our community's electricity need from renewable resources. The majority came from wind and landfill gas harvested from our municipal landfill. While we did generate electricity from solar, the amount was much smaller than these other two sources. This graph shows the contribution of  wind and landfill gas.

Renewable Energy

Columbia's Commercial and Residential PV Systems

From 2007 to 2017, Water & Light customers installed 164 solar electric systems, totaling over 1.5 MW in capacity. This reduces the fossil fuel emissions equivalent to ~230 homes’ yearly electricity use. Columbia Water & Light's Solar Rebate and Loan Programs have been the primary drivers of this increase. Columbia has also committed to purchase all the electricity from a local 10MW solar field. Data source: Columbia’s PV Systems.

Renewable Energy Strategies and Actions

The CAAP process identified strategies for increasing renewable energy generation and procuring renewable electricity. Specifically, setting a goal for Columbia Water & Light to be 100% renewable by 2035. Additionally, the City will maximize the potential for distributed solar PV with solar panels on eligible municipal buildings, expanding incentives for renewable energy installations, and offering a variety of community solar program options. Learn more about all the Strategies and Actions in the CAAP on the Action Plan page.

UNIT
A megawatt hour (Mwh) is equal to 1,000 Kilowatt hours (Kwh). It is equal to 1,000 kilowatts of electricity used continuously for one hour. It is about equivalent to the amount of electricity used by about 330 homes during one hour.

Energy Resilience

Energy Resilience

Increasing grid resilience helps support the City’s energy supply in times of natural disaster and peak energy demand. For example, distributed energy storage can help smooth out the peaks and valleys of wind and solar energy and improve community capacity to maintain electricity with regional outages. Additionally, behavior change can help the utility manage peak demand during the hottest parts of the summer. Reducing peak demand helps the utility and ratepayers save money and prevent outages.

    

Local Energy Resilience

Energy Resilience Strategies & Actions

The CAAP process also identified strategies for maintaining the reliability of local energy supply and distribution, including the development of energy storage programs, the neighborhood resilience hubs and more demand management programs, all of which will bolster the resilience of Columbia’s energy systems.
