Water-efficient shower head

ecocamelJust seen the EcoCamel aerating showerhead – their test results claim a more pleasant shower with almost 50% of the water consumption of a standard shower. At the moment they are £40 for two – not the cheapest option, but a major saving if they work as forecast. Not only do you save water, but also they save the energy required to heat that water – assuming you’re not a devotee of cold showers! Potentially it could also mean that you ned to install less Solar Hot Water panels, which would be a significant saving!

Reducing our Water Charges

Having been looking at increasing our resilience and reducing our impact by using rainwater internally from a large Rainwater Tank, one thing to note is that it can also save us money. Firstly we need to get a meter fitted, so that we’ll only pay our standing charge plus actual water usage. If we’re not using any external water then, according to United Utilities’ Rate Sheet we could be paying as little as £43 a year – saving about £100 a year. Secondly we can apply for a reduction in our Sewerage charges as the water will no longer be entering the sewer. It’s not a huge reduction  – about £34 a year on the fixed charge, plus about £100 a year on consumption charges, but better than nothing! 

So in total we’ll probably save just over £200 a year – not enought o make it a no-brainer investment decision, but certainly a nice bonus for something we were already wanting to do.

Cheaper Solar Panels (update)

Having posted about predictions that cheaper Solar Panels were on the way in 2009 here we are, less than a month later, and cheaper panels are popping up. OK I’m prepared to admin that this might not be a great economic shift – it might just be that I missed this supplier last time. They are Japanese-made Sharp panels and they are £2.99/Watt. I’ve updated the table of prices below – no other prices have changed, but the 200w Kyocera seems to have dropped off the market. Still a little way to go before we get down to the forecast $2.50/Watt!

EDIT – I’ve also added Navitron to the list – not sure how I missed htem first time. Keen prices at £3.72/Watt.

Cheaper Solar Panels

pv_bp7seriesIt seems that cheaper solar panels are on the way in 2009. I’d heard this earlier in the year with regard to new Chinese suppliers coming onstream, but now the forecast drop in prices is accelerating as a result of drop-off in demand from Spain and Germany.

By the end of 2009 average prices for panels for new installation contracts will collapse to the $2.50 to $2.75 per watt range, down from the current level of $4.20 per watt. The overall average price for the year will be $3.10 per watt, Wicht predicted.

 I’ve just done my quick survey of available Photovoltaic Panels, and the lowest price I’ve found is £4.18 /Watt – so it looks like we’ve got a little way to go before we get down to $2.50/Watt!

The downside? Less investment in the industry is likely to result. This, in combination with the lower investement we’re seeing in Oil Exploration & Production as a result of the drop in Oil Prices could have some serious implications for ongoing energy security.

So make sure you get your panels – and then go next door and make sure they’re putting some up too!
