What are Microgrids?

with 60% of the human population set to be living in urban areas by 2030 and pressure on regional and national power grids continuing to grow a number of cities are now turning towards localized energy production for new developments as the name suggests micro grids are small-scale electrical networks that operate independently or in tandem with large-scale electrical supplies while many national and regional electrical grids are now powered in part by renewable energy the majority still depend on nuclear and fossil fuels to deliver the bulk of their power conversely micro grids make heavy use of renewables such as photovoltaics and wind turbines to generate energy for use within a specific building or development this enables them to power their systems and operate without adding to the demands of the winder electrical network on-site energy production and storage can enable a new development to become self-sufficient and help fill in the gaps that can arise on overstretched electrical grids as part of their pledge to honor the 2016 Paris agreement on climate change cities around the world including several in the United States are passing legislation to make all new public buildings and developments in mission free the use of micro grids can contribute significantly to achieving these requirements whilst better insulating large urban areas from potential power failures or blackouts excess energy generated on small-scale systems can be stored on-site for use at a later date or be fed back into wider power grids when necessary whilst legislation is one step private enterprise is also getting on board with micro grids and localized energy production pursuing clear environmental benefits and reduced operating costs developers are beginning to integrate systems from forward-thinking manufacturers and technology entrepreneurs alike one such manufacturer is Polish a uk-based firm have developed transparent photovoltaic Glaus their panels can be used to cover large areas without obstructing views and resemble conventional windows though currently emerging this system could be adapted to cover larger glass buildings in cities around the world allowing them to generate much of their own electricity on a more domestic scale Elon Musk's Tesla solar roof integrates photovoltaics into conventional appearance roof tiles turning entire surfaces into localized power generators this system is integrated with the tesla powerwall allowing excess energy to be stored and used throughout the year many large and small-scale developments are also now incorporating wind turbines to generate power and feed their micro grids reducing their reliance on regional and national power networks energy market analysts Pike research estimate that micro grid power generation has now increased fivefold from 2012 levels and with an increasing array of innovations coming to market we could see entire cities and urban areas powered very differently in the years ahead if you enjoyed this video and would like to get more from the definitive video channel for construction subscribe to the b1m [Music] you
