Small businesses will always strive for ways to reduce their outgoings, particularly in an unfavorable economic climate such as the one we find ourselves in. One good way to reduce expenditure is to look at utilities; switching suppliers or reducing usage can help with energy bills, although it can often be a complicated task.
One way that small businesses are beginning to benefit from attempting to reduce their outgoings is through generating their own electricity. Previously the costs associated with generating electricity prohibited small businesses from considering this option, but generating your own power is becoming a relatively affordable thing to do.
Increasingly generating electricity is becoming a viable option for small businesses, who can pocket the reduced utility bills, and even selling surplus energy back to the National Grid. Here are three ways in which small businesses can generate their own electricity.
Solar Panels
There are two ways in which solar power can be used to generate electricity. Concentrated Solar Power (CSP) uses the sun’s energy to boil some water, while Photo-Voltaic (PV) solar panels convert the energy directly into electricity.
Photo-Voltaic solar panels are still reasonably expensive, but can generate a significant amount of electricity. These are solar panels which use light, so they can still generate power even on grey, overcast days although obviously not as much as long, sunny days.
One problem with solar panels is that they tend to mean power is only available during the day, when the sunlight is casting onto the panels. For domestic properties this can mean that solar panels are not appropriate, but for many businesses the majority of energy use takes place during office hours, when the sun is shining.
Either way, it will be useful to store the energy being generated, so most PV systems come with batteries which can be charged.
Another solution is to sell your energy surplus back to your electrical supplier (as long as you are still connected to the National Grid) and then paying them for your electricity when the sun goes down and you’re no longer generating power.
Wind Turbines
Wind turbines are experiencing a rise in popularity recently, particularly due to the shrinking price of micro-turbines in DIY stores.
While it may seem like the perfect solution, with the wind blowing all day and night, the amount of electricity which can actually be gleaned from these wind turbines is often negligible, depending on the specific location.
Wind speeds are always faster above ground level, at heights above an average house. The wind disturbance caused by other buildings around it further decreases the amount of electricity which can be generated.
A large turbine on the edge of a building where it can receive clean, fast air is more likely to generate a decent amount of energy, but there is also the annoyance of the noise of the blades spinning around.
Combined Heat & Power Units
Another method of generating electricity which is bound to become more widely available in the future is the use of Combined Heat and Power units (CHPs).
While they were previously only suitable for large buildings like factories and universities now small CHP generators are on the market, running on natural gas. The heat generated is channeled to provide heating and hot water for the building and is no less efficient than a modern gas boiler.
Future Benefits
While the technology required to generate electricity may still require a sizable initial outlay, the benefits should be apparent for years and years for a small business, with greatly reduced energy bills. As fossil fuels become scarcer the price of energy is bound to keep rising, so it’s no surprise that forward-thinking businesses are beginning to attempt to run under their own steam.
While these opportunities for businesses to save money on their energy use are still worth investigating, many of the technologies are not yet developed appropriately for businesses, and should probably be considered as future prospects rather than immediate changes.
Save Money Now
Most small businesses could be saving money now by switching business electricity supplier and employing energy-saving measures such as using natural light and ventilation where possible, avoiding leaving equipment on standby and turning off lights in rooms that aren’t in use.
