Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
Many countries are making impressive progress towards integration of distributed renewable energy sources (DRESs) into conventional electricity grids. New management tools backed by a business plan and regulatory framework will ensure a smooth transition.
