Melatonin is involved in the regulation of the sleep-wake cycle, circadian rhythms, and seasonal changes in the light dark cycle. Commonly used to induce sleep, some (but not all) find it to reduce jet lag. There is a high concentration of melatonin in the pineal gland, where it is manufactured. I was surprised to learn that there are significant amounts of melatonin present in the gastrointestinal tract.
In 2014 the average dual fuel reached an eye watering Â£1,344. The average electricity bill was Â£592 and the average gas bill was Â£752. But averages can be confusing. So to give you a better idea of how your own bill compares weâve estimated the total bill for small, medium and large users in the chart above.
(The EPA quotes 50% to 80% savings.) (You can get a 30% tax credit up to $2,000 until Jan. 1, 2008 on a solar water system.) With an average of 400 therms total gas usage, the water heating portion average is on average 50% at 200 therms. Saving 2/3 of this cuts out 200*(2/3)*30=4000 kWh. This cuts the 12,000 kWh down to 8,000 kWh equivalent for gas. At the rate of $1.20 per therm over baseline, the 200 therms saved results in a $240 savings per year.
