Save energy the RUMM way!

Business could save £1bn through energy behaviour change

British companies could save as much as £1bn on their energy bills by changing their ‘energy behaviours’ rather than rely on technical solutions, according to Npower energy experts as reported in the Telegraph this week. Each company could save between 3-15pc, or an average saving of 9pc, the supplier added.

Npower Business Solutions, a division of the Big Six supplier, said that it has already helped customers to drive bills down by £26m after acquiring an energy management firm which specialises in company habits.

Npower snapped up the RUMM energy consultancy in April last year as part of the company’s plan to grow within the increasingly competitive business supply market.

A spokeswoman for the supplier said Npower is targeting total savings of £1bn for its energy customers by focusing on RUMM’s behavioural approach to energy saving for with their sophisticated energy management software and business energy reduction UK
gasEach company could save between 3-15pc, or an average saving of 9pc, the supplier added.

Npower’s Phil Griffiths said: “It often surprises businesses to find out that non-technical savings are usually greater than technical savings. Through learning about your energy habits, it is easy to make subtle, low-cost and effective changes to help keep down your energy bills. It’s already produced clear and proven benefits for firms, big and small, saving businesses we have worked with over £26m.”

The supplier refers to its behaviour analysts as “carbon psychologists” and says that the experts can design energy saving programmes by addressing employee energy habits to help them adopt more energy efficient ways of working.

A study from trade group Energy UK found that the business supply market has seen a consistent increase in competitiveness in recent years. Currently there are 24 suppliers active in the business market of which over a fifth joined the market last year.

Things are constantly changing in the energy sector with many new surprises such as the new Demand Turn Up scheme from National Grid. The idea is that during periods of high renewable generation when the Grid finds it has more energy than it can use, energy-intensive consumers would be encouraged to use more. By either turning off onsite generation from, for example, combined heat and power (CHP) plant or by running an energy-intensive process, such as smelting at a foundry or pumping water at a sewage treatment plant.

A pilot scheme which will run over the summer when wind and solar generation can be high and electricity demand is typically low. Participating businesses will be notified in advance of the extra available energy then, if they respond, they can boost productivity for minimal extra cost plus receive a payment for doing so.

Currently, on very windy days, when output from renewable generation is high the National Grid will turn large power stations down. Or wind turbines themselves may need to be turned off, simply because the power they generate cannot be used.

Filling the energy storage gap

As energy storage technologies become viable utilising energy management solutions it’s likely that storing this extra renewable energy until needed becomes a more cost-effective option. I recently blogged about a 640kWh battery storage system being trailed by Western Power Distribution at a solar farm in Somerset.

Although battery storage systems are predicted to become more efficient and the current high costs to fall, they are not yet able to provide a wide-scale commercial solution to balancing supply and demand. So it will be interesting to see how National Grid’s Demand Turn Up scheme fares.

Have a read of the case study below as to the impact RUMM has had on Cardiff Metropolitan University.

A 7 year Partnership that has accrued more than £1m of savings and reduced the carbon footprint by 15%.

The Client

Cardiff Metropolitan University provides education and training opportunities that are accessible, flexible and of the highest quality. Cardiff Metropolitan has been acknowledged as the “greenest university” in Wales and one of the best across the UK. The University has been a customer of RUMM for over 7 years and the saving accrued are in excess of £1m.

The Brief

As part of the Partnership, RUMM were asked to work with Cardiff Metropolitan to focus upon increasing staff and student engagement by utilising the RUMM aM&T system to provide regular reporting. The goal was to provide reliable and accurate data to inform and motivate management throughout the university.

The Method

Working together, RUMM and Cardiff Metropolitan developed a 5-year plan to reduce utility consumption by 3% per annum. Monthly bespoke reports are prepared and presented to key managers within the University, detailing performance within their respective areas. RUMM’s energy account managers work closely with staff to identify and support Cardiff Metropolitan in realising savings.

Regular meetings are held in order to highlight opportunities for improvement and suggest practical ways in which these can be addressed.

The Results

All targets have so far been exceeded, and Cardiff Metropolitan is has to:

•             Realised financial savings in excess of £1 million

•             Achieved a reduction in its CO2 emissions by more than 15% which is equivalent to the amount of carbon annually absorbed by a forest of 650,000 trees

•             Reduced water consumption by more than 45,000 m3 which is equivalent to 18 Olympic-sized swimming pools

These excellent results have contributed to Cardiff Metropolitan attaining its position as the greenest university in Wales.

Read the instructions below to convert sun into energy

Energy Saving Solution

Make a solar cell in your kitchen

Saving energy is vitally important in these current times. One can explore energy saving systems, however these can be very expensive , we have decided to show you how to make your own solar cell, which is a device for converting energy from the sun into electricity. The high-efficiency solar cells you can buy at Radio Shack and other stores are made from highly processed silicon, and require huge factories, high temperatures, vacuum equipment, and lots of money.

If we are willing to sacrifice efficiency for the ability to make our own solar cells in the kitchen out of materials from the neighborhood hardware store, we can demonstrate a working solar cell in about an hour.

Our solar cell is made from cuprous oxide instead of silicon. Cuprous oxide is one of the first materials known to display the photoelectric effect,in which light causes electricity to flow in a material.

Thinking about how to explain the photoelectric effect is what led Albert Einstein to the Nobel prize for physics, and to the theory of relativity.

Materials you will need

The solar cell is made from these materials:

  1. A sheet of copper flashing from the hardware store. This normally costs about $5.00 per square foot. We will need about half a square foot.
  2. Two alligator clip leads.
  3. A sensitive micro-ammeter that can read currents between 10 and 50 microamperes. Radio Shack sells small LCD multimeters that will do, but I used a small surplus meter with a needle.
  4. An electric stove. My kitchen stove is gas, so I bought a small one-burner electric hotplate for about $25. The little 700 watt burners probably won’t work — mine is 1100 watts, so the burner gets red hot.
  5. A large clear plastic bottle off of which you can cut the top. I used a 2 liter spring water bottle. A large mouth glass jar will also work.
  6. Table salt. We will want a couple tablespoons of salt.
  7. Tap water.
  8. Sand paper or a wire brush on an electric drill.
  9. Sheet metal shears for cutting the copper sheet.

 How to build the solar cell

My burner looks like this:

The first step is to cut a piece of the copper sheeting that is about the size of the burner on the stove. Wash your hands so they don’t have any grease or oil on them. Then wash the copper sheet with soap or cleanser to get any oil or grease off of it. Use the sandpaper or wire brush to thoroughly clean the copper sheeting, so that any sulphide or other light corrosion is removed.

Next, place the cleaned and dried copper sheet on the burner and turn the burner to its highest setting.

As the copper starts to heat up, you will see beautiful oxidation patterns begin to form. Oranges, purples, and reds will cover the copper.

As the copper gets hotter, the colors are replaced with a black coating ofcupric oxide. This is not the oxide we want, but it will flake off later, showing the reds, oranges, pinks, and purples of the cuprous oxide layer underneath.

The last bits of color disappear as the burner starts to glow red.

When the burner is glowing red-hot, the sheet of copper will be coated with a black cupric oxide coat. Let it cook for a half an hour, so the black coating will be thick. This is important, since a thick coating will flake off nicely, while a thin coat will stay stuck to the copper.

After the half hour of cooking, turn off the burner. Leave the hot copper on the burner to cool slowly. If you cool it too quickly, the black oxide will stay stuck to the copper.

As the copper cools, it shrinks. The black cupric oxide also shrinks. But they shrink at different rates, which makes the black cupric oxide flake off.

The little black flakes pop off the copper with enough force to make them fly a few inches. This means a little more cleaning effort around the stove, but it is fun to watch.

When the copper has cooled to room temperature (this takes about 20 minutes), most of the black oxide will be gone. A light scrubbing with your hands under running water will remove most of the small bits. Resist the temptation to remove all of the black spots by hard scrubbing or by flexing the soft copper. This might damage the delicate red cuprous oxide layer we need to make to solar cell work.

The rest of the assembly is very simple and quick.

Cut another sheet of copper about the same size as the first one. Bend both pieces gently, so they will fit into the plastic bottle or jar without touching one another. The cuprous oxide coating that was facing up on the burner is usually the best side to face outwards in the jar, because it has the smoothest, cleanest surface.

Attach the two alligator clip leads, one to the new copper plate, and one to the cuprous oxide coated plate. Connect the lead from the clean copper plate to the positive terminal of the meter. Connect the lead from the cuprous oxide plate to the negative terminal of the meter.

Now mix a couple tablespoons of salt into some hot tap water. Stir the saltwater until all the salt is dissolved. Then carefully pour the saltwater into the jar, being careful not to get the clip leads wet. The saltwater should not completely cover the plates — you should leave about an inch of plate above the water, so you can move the solar cell around without getting the clip leads wet.

The photo above shows the solar cell in my shadow as I took the picture. Notice that the meter is reading about 6 microamps of current.

The solar cell is a battery, even in the dark, and will usually show a few microamps of current.
