An inspiring advocate for science and sustainability, Monica Oliphant has influenced the future of energy consumption around the world. Starting out as a laser physicist, she is now recognised internationally as a pioneer in the use of solar photovoltaics and renewable energy. Monica has devoted her long career – much in her own time and without financial reward – to the promotion of renewable energy both in Australia and overseas. As a senior research scientist with the Electricity Trust of South Australia for two decades, Monica undertook research into renewable energy, with her work enabling grid-connected solar and wind power. Globally-recognised as a leader in her field, Monica has shared her knowledge at conferences in many countries and her work has facilitated development of clean energy policies around the world. Volunteering her time on boards and energy associations culminated in the presidency of the International Solar Energy Society. Monica has maintained a lifelong commitment to improving all people’s access, particularly those of lower socio-economic status, to environmentally and economically sustainable energy.
