I have set up this environmental themed caching series so that people will learn how easy it is to make small changes in their lives that will benefit the environment, and can also save them some money as well.
A carbon footprint is the total set of GHG (greenhouse gas) emissions caused directly and indirectly by an individual, organization, event or product. An individual, nation or organization's carbon footprint is measured by a GHG emissions assessment. Once the size of a carbon footprint is known, a strategy can be devised to reduce it.
Carbon offsets, or the mitigation of carbon emissions through the development of alternative projects such as solar or wind energy or reforestation, represent one way of managing a carbon footprint.
Low Energy Lights Bulbs
Low energy light bulbs use less than 20% of the energy of a conventional light bulb, and can last up to 15 times longer.
Fitting Low Energy Light Bulbs is simple, helps the environment and should reduce your lighting bills.
Here is an example:
A $0.99 standard 100 Watt light bulb that is operational 24 hours per day, 7 days per week. This fixture will use 870 kW/h over a year, at $0.7 per kW hour, it will cost you a little over $61.00 for the year, with a gross cost including purchase of $62.00.
Compare this to a 28 Watt compact fluorescent light bulb, which costs approximately $21.00 to purchase. This fixture replaces the old 100 Watt fixture, and provides the same light intensity. It will consume 244 kW/h per year and cost you $16.50 in electricity costs for the year, with a gross cost of $37.50 for the year.
So, which is the most expensive bulb at the end of the year? The compact fluorescent is a clear winner. Factor in that the compact fluorescent fixture will outlast a conventional bulb by upwards of 10x (or more), it continues to pay for itself long after the "cheap" bulb has burned out a few times.
Did you know? If all 12 million households in Canada replaced 16, 60-watt incandescent lightbulbs with 15-watt CFC lightbulbs, it would reduce the same amount of greenhouse-gas emissions as taking 1 million cars off the road.
To find the cache location, answer the following questions.
A) Low energy light bulbs use less than _ _ % of the energy of a conventional light bulb.
Find the missing value, and multiply it by 44.6 to get the last 3 digits of the North coordinates.
B) Low energy light bulbs can last up to _ _ times longer than a conventional light bulb.
Find the missing value, and multiply it by 62.6 to get the last 3 digits of the West coordinates.
There is a prize in the cache, for the first 3 finders.
