March 24 – Buy Energy-Saving Lightbulbs

“The girls who were wise answered, ‘There’s not enough oil for all of us!’” ~ Matthew 25:9   Everyone or rather all buildings are dependent on light bulbs, individually light bulbs are not major energy consumers in building but when considered collectively, they use a significant amount of energy. Lightbulb manufacturing has been undergoing an energy-saving revolution in the recent years. There are 3 types of lightbulbs, namely; Incandescent light bulbs; Compact florescent lights (CFLs) and Light-Emitting Diodes (LEDs). LEDs are the most advanced lightning technology on the market.  LEDs are the most energy efficient lightbulbs available on the market and they also have a considerably longer lifespan. Advantages of using energy saver bulbs(LED): Energy efficient- LED lights are up to 80% more efficient than traditional lighting such as fluorescent and incandescent lights. 95% of the energy in LEDs is converted into light and only 5% is wasted as heat. This is compared to fluorescent lights which convert 95% of energy to heat and only 5% into light! LED lights use much less power than traditional lighting; a typical 84 watt fluorescent can be replaced by a 36 watt LED to give the same level of light. Less energy use reduces the demand from power plants and decreases greenhouse gas emissions. No toxic elements- LED lights contain no toxic elements. Compact Fluorescent lights contain noxious chemicals such as mercury. These elements contaminate the environment when disposed of in landfill waste.  LED bulbs helps to protect the environment from further toxic waste. Less lights needed- LEDs have a better quality of light distribution and focus light in one direction as opposed to other types of lighting which waste energy by emitting light in all directions, often illuminating areas where light isn’t required. Less LED lights are needed to achieve the same level of brightness given off by fluorescents and incandescent lights. Fewer lights will reduce energy consumption and will therefore be a benefit to the environment. Life span- LED Lights last up to six times longer than other types of lights, reducing the requirement for frequent replacements and therefore decreasing the resources needed to manufacture lightbulbs. A longer life span will result in lower carbon emissions.

March 23 – Turn Down the Heater

“It serves as fuel for man. He takes some of it and warms himself; also he kindles a fire and bakes bread.” ~ Isaiah 44:15   There is nothing like taking a hot shower to wash away the worries of our day. But too much of a good thing is NOT a good thing. Water heating accounts for 15 to 25% of energy consumption in the average home. For every 10 degrees you turn down your water heater, you’ll save 3% to 5% on your bill. Most water heaters come pre-set at 140 degrees, which has the added risk of scalding. It is recommended that households lower it to 120 degrees. This amount is high enough for your needs, and high enough to reduce mineral buildup in your tank and pipes. A fridge/freeze is an appliance one uses on a daily basis and it is normally kept on 24/7. Fridges form part of our energy consumption.  Refrigerators and freezers should not be set too cold. It is recommended to set your fridge between 4-5°C  and the freezer to -18°C  .If you set fridge or freezer 1°C  colder, it increase your energy consumption by 5 to 10% and therefore increase your electric bill. Steps to turn down water heater: Find the current temperature- use a thermostat to measure the temperature your water is at now. At the tap furthest from the water. Mark the setting- to remember this setting, mark that temperature on your thermostat. Now turn down the thermostat to what you think will be 120 degrees, based on your earlier measurement. Wait at least 2 hours. Measure the water temperature again at the same far-away tap. It may take a few attempts to get it right. Once it’s right, mark that spot on your thermostat so you’ll remember the new temperature. How to turn up the fridge using a thermostat: To check your refrigerator’s temperature, set a thermostat in a glass of water in the center of the appliance. Read the thermostat after 24 hours. For a freezer, place a thermostat in between packages. Again, read the thermostat after 24 hours.

February 29 – Pledge to Save Energy & Fuel

There are lots of actions we can take to reduce our fuel and energy consumption To use less fuel we can commit to using the car less, walking or cycling for short journeys, car pooling. As churches and Dioceses we can look at how we do meetings – can some of them to change to video conferencing or Skype calls? For those of us who fly, the impact of air flights is enormous. Let us choose holidays that do not involve flying, send a video message to a conference rather than attending in person. To use less energy, we can look at our household use and turn up or down thermostats on water heaters and fridges, choose a fan instead of air con, purchase energy saving lights or electronic gadgets, put insulation in our homes, move to renewables if we can. But do these individual actions matter? I will share some insights from Rev Fletcher Harper “Why are we, as individuals, asked to change our lifestyles when the climate crisis is arguably not due to personal deficiency? Our power as consumers is strong but asking individuals to bear the burden of global warming can shift responsibility and accountability away from those causing the vast majority of climate change. Consider this: A recent report found that just 100 companies are responsible for a whooping 71% of global emissions since 1988. Incredibly, only 25 corporations and state-owned entities were responsible for more than half of global industrial emissions in that same period. Most of these are coal and oil producing companies and include ExxonMobil, Shell, BP, Chevron, Gazprom, and the Saudi Arabian Oil Company. And so I wondered: What can I do, as an individual, that actually matters, and what do we need to do together to slow the increasingly destructive effects of climate change? Here is where we come down on this: it’s not EITHER/OR, it’s YES…AND. Of course, we need to consume less and choose more low-carbon alternatives. But individual choices will most count when we also come together in bold collective movements to hold accountable those who cause the greatest damage. Here is how we are thinking about this: YES, low-carbon individual choices are important. Here are some reasons: As important as the carbon impact of our individual choices, though, is the fact that every act  is changing norms with a wider knock-on effect that influences others, and shifts what is viewed as ‘normal.’ To give you an example: In a survey that a researcher conducted in 2018, an impressive half of the respondents who knew someone who has given up flying because of climate change said they, in turn, fly less. Around three quarters said it had changed their attitudes towards flying and climate change in some way. And these effects increased if a famous person had given up flying.   Taking a bold position (like becoming a vegan or giving up flying) really distills the link between values and actions. And, as you well know as a person of faith: It’s important to live a life where values and actions align. That also makes us much more credible messengers when we speak about the importance of action on climate change. So – talk about what you are changing in your life in response to climate change. It may have a powerful ripple effect”. Rev Fletcher Harper , Green Faith Image by congerdesign from Pixabay
