What Are The Best Power Solutions For Our Future Needs?

Renewable power sources (called "renewables") offer a variety of alternative energy sources with the potential to meet all of our energy needs. Geothermal and solar energy alone could each supply 250 GJ per year to 10 billion people, assuming economically viable technology is available. With the exception of Asia and Europe, most regions of the world could be self-sufficient. However, the widespread use of these intermittent sources of energy will depend on the development of new forms of energy storage and competitive economics.

How Do I Save Power In The Office?

One area that typically costs SMEs more than they think is their energy costs. The good news is that you can reduce your energy expenditure by making your business more energy-efficient. A quick Google search gives you loads of energy-saving tips, but we’ve compiled our favourites here. Some require planning and investment, others can be implemented for free in a matter of minutes. Some take advantage of the latest technology, some come down to good old-fashioned common sense.


Switch to energy-efficient light bulbs. LED bulbs can help you save as much as 80% on lighting. Make use of natural light from windows and skylights. Don’t rely on artificial light when it’s bright outside – save it for gloomy days and dark evenings.


Remind employees to switch off all computers and other equipment that isn’t being used. If people need a little extra encouragement or they’re worried about powering down essential equipment, E.ON recommends introducing a traffic-light system: a red sticker means don’t turn off, an amber sticker means only authorised people can switch the appliance off, and green means anyone can

How Does Uninterrupted Power Supply Work?

An uninterruptible power supply (UPS), also known as a battery backup, provides backup power when your regular power source fails or voltage drops to an unacceptable level. A UPS allows for the safe, orderly shutdown of a computer and connected equipment. The size and design of a UPS determine how long it will supply power.

A standby UPS resorts to battery backup power in the event of common power problems such as a blackout, voltage sag, or voltage surge. When incoming utility power drops below or surges above safe voltage levels, the UPS switches to DC battery power and then inverts it to AC power to run connected equipment. These models are designed for consumer electronics, entry-level computers, POS systems, security systems, and other basic electronic equipment.

How Do I Calculate My Power Needs?

Small power is a substantial energy end-use in office buildings in its own right, but also significantly contributes to internal heat gains. Technological advancements have allowed for higher efficiency computers, yet current working practices are demanding more out of digital equipment.

So, how is electricity measured? This is an important question to begin to understand how an electricity tariff works. Electricity power is measured in terms of units, called watts. Most appliances in a household require well in excess of 1,000 watts in order to function properly, which is why we generally refer to electrical power as kilowatts. Each kilowatt represents 1,000 watts. So how is this calculated? If you take an example of a 100-watt ceiling fan and use it for two hours a day for 30 days, you have used 100 watts of power for 60 hours.

This calculates as 100 watts x 60 hours = 6000 watt-hours of electrical energy. Or 6 kilowatt-hours (kWh) which is the measurement of electricity units.

What Happens If There Is A Power Failure?

Power outages have generally direct and indirect effects on the overall performance of firms, causing increases in economic costs, reductions in produced quantities, and eventually decreases in sales and productivity.

How Do I Keep My Business Running When The Power Goes Out?

For most small businesses, a power outage in the workplace can create a huge drain on the bottom line. In addition to power outage safety concerns, outages mean lost time, lost customers and lost productivity, which all translate to lower revenue. Luckily, with a few basic power outage tips, you can minimise the impact of when the power goes out. Knowing what to do during a power outage at work is key to keeping your employees and customers safe and profit losses down. For instance, if you have a brick-and-mortar location, a power outage means that customers may not be able to visit your store. An outage also means no internet—and not being able to respond to email inquiries in a timely fashion.

Business Continuity Plan At The Hand Of Power Solutions

A power outage business continuity plan must be included in an organisation's incident response protocols. Organisations can also take various measures to minimise the likelihood of power outages, such as infrastructure testing and ensuring ample backup power supply access.

Periodically inspect the building infrastructure for power protection equipment, including the following:

  • lightning arrestors;
  • power conditioners;
  • surge suppressors;
  • diverse cable routing in vertical and horizontal raceways and cable paths;
  • diverse power cable routing into the building; and
  • service from two different utility power substations.

Ensure that emergency lighting is in place throughout each floor of the office and in stairwells. If an organisation is a tenant in an office building or manufacturing facility, check with the facilities management team on their power protection activities.

Inverter For Power Solutions

An inverter converts the DC voltage to an AC voltage. In most cases, the input DC voltage is usually lower while the output AC is equal to the grid supply voltage of either 120 volts, or 240 Volts depending on the country.

The inverter may be built as standalone equipment for applications such as solar power, or to work as a backup power supply from batteries that are charged separately.

The other configuration is when it is a part of a bigger circuit such as a power supply unit, or a UPS. In this case, the inverter input DC is from the rectified mains AC in the PSU, while from either the rectified AC in the UPS when there is power, or from the batteries whenever there is a power failure.

There are different types of inverters based on the shape of the switching waveform. These have varying circuit configurations, efficiencies, advantages, and disadvantages

An inverter provides an ac voltage from dc power sources and is useful in powering electronics and electrical equipment rated at the ac mains voltage. In addition, they are widely used in the switched-mode power supply inverting stages. The circuits are classified according to the switching technology and switch type, the waveform, the frequency, and the output waveform.

UPS For Power Solutions

An uninterruptible power supply (UPS) offers guaranteed power protection for connected electronics. When power is interrupted, or fluctuates outside safe levels, a UPS will instantly provide clean battery backup power and surge protection for plugged-in, sensitive equipment.

Downtime caused by power outages is frustrating for anyone, but can be financially crippling for a business or organisation. Every year, billions of dollars are lost due to downtime caused by power disruptions that could have been prevented by a UPS.

Electronics have both maximum watt ratings and maximum VA (volt-ampere) ratings. Neither rating may be exceeded by the attached equipment. Watts measures real power drawn by the equipment, while volt-amps are the product of the voltage applied to the equipment times the current drawn by the equipment.
