Energy conservation is mostly common sense, yes, but sometimes we can all use a few reminders. What does Accounting and Climate Change have in common? A lot in fact. If you ask Sanjay Kumar what the link is, the most likely answer he would give is everything. Most stories on Climate Change describe the science behind this natural phenomenon but hardly talk about the actual costs of climate change. Sanjay is the Finance and Administration Manager for the WWF South Pacific. Naturally, being an accountant has taught him to be frugal; not only with money but also in his family’s consumption of electricity and water. What makes this accountant such a greenie? It’s a mixture of simply wanting to save money and the influence of spending more than a decade in service to WWF South Pacific. For Sanjay the only ‘natural way to go’ was to go green. Sanjay’s enthusiasm to go green is literally turning energy and water efficiency into hard cash and he is starting from home. In doing so, he has also made the stark connection to the national level. As a part of the 2011 Earth Hour campaign, the slogan for Fiji is to make the “switch”. Sanjay is putting his unique twist on it by making the most out of rain water. “We know that water from the taps is not as clean as we think, it costs money and is unreliable as the supply to most communities shuts down frequently,” Sanjay says. “I used piped water for almost everything in and around the house. I would use it to clean the driveway and the footpath, use it for the washroom, water my vegetable garden, the laundry, cleaning dishes and for taking showers.” Utility bills are skyrocketing and to make some savings I had to first assess how much water I was actually using every day. “Upon analysing my water bill I noticed that I used 101 units in 3 months and one unit of water is equivalent to 1000 liters. Most of the cost came from expenses that I could have easily avoided. Knowing more now about alternative energy saving methods from work I decided to invest in a more environmentally friendly way of saving money.” Here queues the drum rolls. The water tank! It is simply a system that collects and stores rainwater from the roof that would otherwise be lost to runoff and diverted to drains. Rainwater by nature is a soft water, void of harsh chemicals or pollutants, usually hitting the soil in its purest form. It is the most precious source of freshwater on earth, and the most readily available. “As we know it is raining most of the time in the greater Suva area, or if it has not rained for a while, when it finally does rain it pours. And the amount of rain easily fills up any water tank.” “Collecting rainwater is so easy everyone should do it. The area of your rooftop helps to gather large quantities of water. You can consolidate this and collect gallons of water, and it's all free.” “I have simply connected the water tank to the guttering. In doing so I have been able to offset most of our water usage by using the water collected for the toilets, to water my backyard vegetable garden, wash the drive way, cleaning dishes and to clean the car [which I do once a month]. This way I save a lot on my water bill.” “At the government and business level making the switch to using rain water would mean a reduction in capital cost of water pipes etc, fuel cost of transportation and running water plants, labour cost, cost of importing chlorine and an overall reduction in carbon dioxide emissions which would allow Fiji to meet its global pledge to cut down on CO2 emissions.” Therefore it makes eco-sense and dollar cents to conserve water (and remember, the less hot water you use, the less energy you pay for as well). Finally, if you're in the process of building a new home or adding an extension, it's worth considering what options you have to make it more environmentally friendly. In recognition of the importance of energy saving, don’t forget on March 26 at 8.30 PM switch off your lights for Earth Hour and make the long term switch for your pockets and for the environment. Earth Hour has created history as the largest voluntary action ever witnessed with participation across 128 countries and every continents, including the world’s most recognised man0made marvels and natural wonders in a landmark environmental action. Join Sanjay and millions of people across the world in this campaign, be part of the green movement and make the switch.
