Renewables, including solar, wind, hydropower, biofuels and others, are at the centre of the transition to less carbon-intensive and more sustainable energy systems.
Are solar and wind power the future of energy?
Solar and wind power, among other renewable sources, are leading the charge toward a more sustainable future, but beyond these well-known technologies, there are new frontiers emerging in the quest for clean, limitless energy.
Some storage technologies today are shown to add value to solar and wind energy, but cost reduction is needed to reach widespread profitability.
Is solar storage more valuable than wind?
Storage is more valuable for wind than solar in two out of the three locations studied (Texas and Massachusetts), but across all locations the benefit from storage is roughly similar across the two energy resources, in terms of the percentage increase in value due to the incorporation of optimally sized storage.
How does wind power work?
The blades are connected to a generator that converts the kinetic energy into electricity. Wind power installations have grown worldwide, with leading countries like China, the US, and Germany pushing for increased capacity, as seen in the Global Wind Energy Council's report. Solar energy is another powerhouse among renewables.
Energy storage can transform intermittent renewables for this purpose but cost improvement is needed. Evaluating diverse storage technologies on a common scale has proved a major challenge, however, owing to their widely varying performance along the two dimensions of energy and power costs.
Storage can increase the revenue generated by a solar or wind plant, but it also increases the capital costs of the plant. Here we optimize both the discharging behaviour, as done above, and the storage system size, to maximize the value of the electricity generation.
