Clean Energy Project Screening Tool


We have developed a prototype 'shortcut' low carbon energy concept screening tool. The aims of this (and the customer problems we're trying to solve) have been developed based on years of experience and are discussed in our Why page.   This tool enables us to provide quick, cost effective concept exploration and screening service to aid in quick investment decisions.

The infographic below summarises how the elements of a project flow and are linked together:

Olwg Clean Energy Project Screening

Using our unique tool we can quickly assess and evaluate a number of clean energy concepts to determine which options is the best solution in terms of economics and sustainability for your project.

Olwg Unit Converter

There are several different units used to measure energy: joules, BTUs, newton-meters and calories to name but a few. 

When considering electrical energy, the most common unit is the watt-hour. One watt of electrical power, maintained for one hour, equals one watt-hour of energy. A thousand of these is a kilowatt-hour (kWh), and note that a thousand watts for one hour, or one watt for a thousand hours, both equal one kWh. They’re the same amount of energy.

So a kilowatt hour (kWh) is a measure of how much energy you’re using.  It doesn’t mean the number of kilowatts you’re using per hour. It is simply a unit of measurement that equals the amount of energy you would use if you kept a 1,000 watt appliance running for an hour:

So if you switched on a 100 watt light bulb, it would take 10 hours to rack up 1 kWh of energy. Or a 2,000 watt appliance would use 1 kWh in just half an hour. While a 50 watt item could stay on for 20 hours before it used 1 kWh.

What’s the difference between kWh and kW?


  • A kilowatt is simply 1,000 watts, which is a measure of power. 

  • A kilowatt hour (kWh) is a measure of energy.


So a 1,000 watt drill needs 1,000 watts (1 kW) of power to make it work, and uses 1 kWh of energy in an hour.

This all gets very confusing and this is before you change units consider that this is only for electrical power, mechanical power and heat are different concepts again.   Changing units confuses things further still.

At Olwg we have developed a unit converter to help demystify all of this. This is a free to use tool, but you must be logged in to use it. 


Our unit converter is still in the development stage.  If there is anything you think we've missed or would like to see added, please let us know


Energy Project Consulting


We also offer a variety of value-adding services to support energy engineering projects. From the initial stages for concept screening and selection to project planning and assurance.  We are natural-born collaborators.  We use a team working approach to provide quick, cost effective solutions delivered in a way that is easily understood by all decision makers.

We have a  deep and broad industrial heritage with more than 20 years' global experience in upstream oil and gas developments covering:

  • Traditional chemical and process engineering.

  • Development planning.

  • Project management.

  • Process operations optimisation.

  • Modern operational techniques.

Our background and knowledge of traditional engineering projects and operations is the foundation we use to approach all energy-related project problems. 

We have the capability to look at solutions to many decarbonisation challenges, big or small, complex or simple, technical or organisational.  We have the knowledge and experience to help at any stage of the project.    

Our services at Olwg can be broken down into three core areas:​
