Market overview

Market overview

Energy is an integral part of the modern world, with engineers and technicians facing challenges around global energy needs. The rising importance and recognition of climate change and the growing world demand for energy has brought the topic to the forefront of the public and political agenda. As a result of this, a rethink of the agenda on a global scale is required.

Global landscape

The global consumption of marketed energy is predicted to increase by 49% from 2007 to 20351, with non-OECD economies accounting for the largest projected increase in energy demand.

Electricity continues to be the world’s fastest growing form of end-use energy consumption. Due to rising living standards, net worldwide electricity generation is predicted to rise by 2.3% per year from 2007 to 2035, with the strongest growth in non-OECD countries2. In some OECD countries there is the significant probability of a switch to electricity for road transport and the replacement of gas fuel for heating with electrically driven heat pumps. This could double electricity demand within the same timescales.

This results in an energy paradigm shift, with the sector becoming a key focus for policy makers and investment, creating a huge demand for professional skills. Issues and challenges vary from country to country, presenting an opportunity for the IET to be the natural home for the global energy community.

UK landscape

The UK employs 121,000 people in the electricity, gas and steam supply industries and these companies have an annual turnover in excess of £93 billion3

Energy & Utility Skills (EU Skills) has estimated that the power industry will need to recruit 35,000 new employees by 2024. It is vital that the quality of education and skill providers are increased to train these new recruits. This challenge is in addition to the need for extra training of staff and managing the loss of 80% of its current workforce as they retire. There has never been a more exciting time to work in the energy sector.

Industry outlook

To take the UK as a case study, the following outlines potential future developments in the energy sector.

  • a major programme to construct renewable energy generation is under way. The aim of this is to result in over 30 GigaWatt (GW) of new capacity by 2025 (compared with a total energy installed capacity of 75 GW in 2011
  • new nuclear remains a key part of UK energy policy (despite the incident in Japan), with around 15 GW likely to be built over the next 15 years
  • public sector investment in the hundreds of millions of pounds to support the demonstration at scale of carbon capture and storage from coal generation is continuing, despite budget cuts. If successful, this would result in many GW of new coal generation
  • extensive investment in efficient use of energy, smart demand, smart grids and other new technologies will be needed to allow an electricity system with a large amount of renewables to operate
  • a way to manage an electricity system characterised by variable supply and partially controllable demand will need to be developed
  • new energy storage technologies are under intensive development
  • new transmission will need to be built, a large part of it offshore
  • large scale infrastructure is required to support the development and mass deployment of electric or hybrid personal transport
  • major interconnections across Europe remain a possibility to share variable renewable energy and potentially give access to global renewable resources
  • cost – approximately £250 billion by 2025

The above points, coupled with an ageing infrastructure and an environment where achieving public acceptance of new infrastructure is increasingly difficult, highlighting the huge challenge ahead.

The fuel mix for the UK’s electricity supply remains heavily reliant on gas and coal (Figure 1). In addition to the need to move towards a low carbon economy, there is also the challenge of ensuring a secure supply of oil, gas and electricity.

The IET has core strength in the energy industry, in particular the fields of electrical power transmission and distribution. Through this sector the IET will look to further its position as an industry thought leader.
