October is National Energy Awareness Month! In 1991, President Bush proclaimed the month of October a time to raise awareness and take action to manage America’s energy resources sustainably. It’s an important topic, but often energy efficiency and sustainable energy get forgotten in the background of people’s busy lives. Electricity is everywhere, but we sometimes take for granted all of the things it allows us to use. We usually don’t stop to think about electricity unless prices go up or a power plant or a new pipeline is installed nearby. How we use energy and where it comes from has a big impact on our wallets, security, economy, and the communities we live in, not to mention what future generations will have to face, so it’s crucial to pay attention and make a concerted effort towards sustainable energy.
There are some energy savings tips that get a lot of buzz – things like upgrading to LED bulbs, replacing old appliances, or washing with cold water. Efficiency is a big part of sustainability, and for most people making these kinds of changes is not too difficult. There are also programs such as Mass Save which will do free home energy audits and install free or discounted energy saving measures such as light bulbs and insulation, as well as make recommendations and educate homeowners on the energy systems in their house.
It’s important to focus on this not just at home, but also at work. As of 2012, commercial use accounted for “…nearly 20% of US energy consumption and 12% of the nation’s greenhouse gas emissions.” Public and commercial buildings are often fully powered even when occupancy rates are low. Measures such as motion sensors, more efficient appliances, and encouraging participation and action by the building’s occupants can help with commercial efficiency.
Bringing usage down is a good first step towards a stable, sustainable energy future, but we still get most of our power in the US from non-renewable sources. Just shy of 63% of our energy came from fossil fuels in 2017. Another 20% came from nuclear power. Even the most efficient building can’t run forever on a finite fuel source. This is where renewable energy sources come in. Once power is generated and in our homes and businesses, it’s all the same, but where it first came from makes a big difference in the price we pay, the pollution we see, and the reliability of our grid.
In 2017, 17.1% of our energy came from “renewables” – that’s anything that can naturally replenish itself after we use it to generate power. This includes things such as wood, landfill gas, solar, geothermal, wind and hydropower. Some of these issue more pollution when they’re used than others, and it will take a mix of them to meet our power needs.
