As an engineer, you have a unique opportunity to shape a sustainable future. With climate change posing significant challenges, the demand for sustainable solutions across all industries is skyrocketing. From renewable energy and green construction to eco-friendly product design and waste management, engineers are at the forefront of driving sustainability initiatives.

Renewable energy engineering

Ireland has set a target to generate 80% of its electricity from renewable sources by 2030, presenting opportunities for renewable energy engineers. Wind Energy Ireland estimates that Ireland will need to deploy around 8.2GW of offshore wind energy to meet these targets, which will require a skilled renewable energy engineering workforce.

As a renewable energy engineer, you could be involved in designing and constructing offshore wind farms, solar farms, or hydroelectric dams. You might also work on improving energy storage solutions to ensure reliable power supply from intermittent renewable sources.

One notable project is the Arklow Bank Wind Park, with Phase 1 constructed in 2003/04 consisting of seven turbines with a 25.2 MW capacity – Ireland’s first and only operational offshore wind farm to date. Future phases are planned to expand it up to 800 MW through a €2.5 billion investment.

Careers in Sustainability for Engineers

Green building and construction

The Irish government has introduced initiatives like the Nearly Zero Energy Building (NZEB) standard, which aims to make all new buildings in the country nearly zero-energy. This has created a demand for green building engineers who can design and construct energy-efficient, sustainable buildings.

As a green building engineer, you could specialise in designing energy-efficient buildings that incorporate sustainable materials, optimise natural lighting and ventilation, and implement renewable energy systems like solar panels or geothermal heating and cooling.

A prime example of sustainable construction is the new state-of-the-art STEM facility at Dundalk Institute of Technology (DkIT). This cutting-edge building incorporates energy-efficient design principles and sustainable materials, positioning DkIT as a leader in promoting environmentally responsible education infrastructure.

Sustainable transportation engineering

The transportation sector contributes to greenhouse gas emissions and air pollution. Engineers are developing sustainable transportation solutions to reduce these environmental impacts.

As a sustainable transportation engineer, you could work on designing and developing electric vehicles, optimising battery technologies, improving charging infrastructure, and integrating smart energy management systems.

Additionally, engineers are essential in improving public transportation systems, such as designing efficient rail networks, optimising traffic flow, and implementing intelligent transportation systems to reduce congestion and emissions.

A notable sustainable transportation project is the DART+ Programme, which aims to significantly expand the electrified rail network in the Greater Dublin Area.

Careers in Sustainability for Engineers

Environmental engineering and sustainability consulting

Environmental engineers and sustainability consultants help organisations reduce their environmental footprint and implement sustainable practices.

As an environmental engineer, you could work on developing and implementing waste management systems, water treatment solutions, air pollution control technologies, and soil remediation strategies. You might also be involved in conducting environmental impact assessments and ensuring compliance with environmental regulations.

Sustainability consultants provide expertise and guidance to organisations seeking to integrate sustainability into their operations, products, and services. This could involve conducting energy audits, developing sustainability strategies, implementing environmental management systems, and advising on sustainable product design and lifecycle analysis.

One example of a sustainability consulting project is Diageo’s planned investment at the St. James’s Gate brewery in Dublin, which aims to accelerate the site’s transition to net-zero carbon emissions.

Careers in Sustainability for Engineers

Research and academia in sustainability engineering

Engineers contribute to sustainability through research and academic pursuits, advancing our understanding of sustainable technologies and practices.

As a researcher or academic in the field of sustainability engineering, you could focus on developing new sustainable materials, improving energy efficiency algorithms, or exploring innovative renewable energy technologies. You might also conduct research on sustainable manufacturing processes, circular economy models, or ecological engineering solutions.

Additionally, academics in sustainability engineering play a vital role in educating and training the next generation of engineers, equipping them with the knowledge and skills necessary to tackle the sustainability challenges of the future.

Several universities, such as University College DublinTrinity College Dublin, and University College Cork, have dedicated research centres and academic programmes focused on sustainability engineering and related fields.

The transition towards a sustainable future presents numerous career opportunities for engineers across various industries and disciplines. Whether it’s renewable energy, green construction, sustainable transportation, environmental engineering, or sustainability consulting, engineers are at the forefront of developing and implementing sustainable solutions.
