Community Energy in Context

Managing for energy at the community scale can promote more sustainable and secure energy futures, while reducing carbon emissions that contribute to global warming.

With clear and compelling visuals of Metro Vancouver case studies, and new information on regional and local energy sources, this web-resource aims to inform citizens about renewable energy options as well as energy conservation measures, and stimulate discussion about the energy choices that communities are increasingly facing.

What is Community Energy?

Neighbourhoods can save, generate and share energy

Community energy means local efforts to manage how we use energy and where our energy comes from. It includes multiple energy sources, distribution networks, and planning practices, policies and behaviours, implemented at neighbourhood and community scales. This usually means some degree of local involvement in the management and control of the system, with sharing of responsibilities, benefits (including revenue), and impacts among the community.

Energy and Climate Change

USING FOSSIL FUELS TO MEET OUR ENERGY NEEDS IS THE MAJOR CAUSE OF CLIMATE CHANGE

The burning of fossil fuels for energy production releases carbon dioxide and other gases into the air. These gases trap the sun’s reflected radiation in our atmosphere. This condition is leading to changes in our climate and overall, global warming.

Scientists have determined that a global warming beyond 2 degrees Celsius is a serious threat to the lives of current and future generations, especially amongst the world’s poorest populations. In order to avoid the most serious impacts of global warming we must substantially reduce the greenhouse gases we emit into the atmosphere.

BRITISH COLUMBIA’S COMMITMENT TO CLIMATE CHANGE

In response to the reality of climate change, British Columbia committed to taking action, and in 2007 showed world-wide leadership by legislated greenhouse gas emissions targets and other provincial and local government policies to help mitigate climate change. Municipalities in BC were quick to follow suit, and many have pledged to reduce their community-wide greenhouse gas emissions by up to 80% by 2050—our share of the worldwide reduction necessary to maintain an average global warming of 2 degrees.

Metro Vancouver Demand

How does our region use energy?

Communities across the region use different total amounts of energy for electricity, heating, and transportation. We also consume different amount of energy per person across the region, depending on which municipality we live in (due to their housing types, land uses, transport options, and energy/climate change policies).

Is our Energy Clean?

Where does energy come from in British Columbia?

Much of the energy currently used in Metro Vancouver homes comes from remote suppliers in BC and Alberta, at least 400-1000 kilometers away. Natural gas to heat our homes is piped from northeastern BC and Alberta. Electricity to power our homes comes primarily (approximately 90%) from Hydroelectric dams in southeastern and central BC. This hydroelectricity is supplemented by natural gas electricity generation in BC and, at times, by other fossil fuel-based generating plants in Alberta and the United States.

Metro Vancouver is also crossed by railways and pipelines which ship coal and oil from the oilsands for export. A small portion of the oil that is exported is imported back to Canada to meet our transportation needs.

Local Energy Economies

What if our money stayed in our communities?

A community energy system based on renewables can be less vulnerable to global energy markets. After an initial investment in a system, operation costs remain generally low.

District Energy Facilities

A district Energy system can generate heat and electricity for distribution

A district energy facility generates heat and sometimes elecrticity for distribution to local users. District energy is more energy efficient then using individual building furnaces for neighbourhoods with adequate density, and therefore reduces greenhouse gas emissions, especially when using renewable supplies.

Housing, Design & Retrofits

Energy can be saved by bringing existing buildings up to new, more efficient standards

Significant energy can be saved by bringing existing buildings up to more efficient standards. Basic retrofits such as adding solar hot water can reduce total energy use by up to 30% and greenhouse gases by 33%. Major retrofits such as adding air source heat and other renewables can reduce total energy use by 75% and greenhouse gases by 80%.

Behaviour

MANAGING ENERGY DEMAND – INDIVIDUAL ACTION

Individuals can change their energy behaviours by choosing actions like using more efficient light bulbs and Energy Star appliances in your home, putting on a sweater instead of turning up the heat, or retrofitting your house to improve its insulation. According to BC Hydro, if you turn down your heat by just two degrees, you can reduce your home heating costs by 5%.

Behaviour

MANAGING ENERGY DEMAND – COLLECTIVE ACTION

Managing energy efficiency can also happen at the community-wide level (collective action). Municipalities can adopt land use and transportation plans and policies that place higher density homes close to services—and support transit, pedestrians and cyclists—to encourage people to drive less. Higher densities also support more efficient and cost-effective community energy solutions, such as a district heating system. With people living closer together, they will share building walls, which greatly reduces the amount of energy needed to heat a home. Local governments can adopt policies and programs to assist homeowners in energy efficient upgrades, such as rebates or on-bill financing for the installation of energy efficient heating and hot water systems and building envelope improvements.

Behaviour

MANAGING ENERGY DEMAND – Managing Energy Supply

Another way communities can mitigate climate change is by switching to clean, or renewable energy sources—energy supplies and systems that minimize, or eliminate completely, the production of greenhouse gases. This will be a critical move for municipalities to make to meet a target of 80% greenhouse gas reduction by 2050.
