DC Lighting & Renewable Power Information

Featured

WHY DC?

DC Technology

DC Lighting

  • Innovation and lower cost are driving the DC lighting market.

Efficiency

  • Minimizing power conversions can save energy in any electrical system, and LED lighting is a good match for a DC grid and also renewable energy such as solar power in green buildings.

Applications & Uses

DC Microgrid

Simplified depiction of (a) a typical AC building microgrid and (b) a typical DC building microgrid.

  • THERE ARE several factors driving local, regional, and national electricity distribution towards direct current (DC).
  • Ken Erdmann of Erdmann Electric discusses a DC powered home.

DC Powered Buildings

  • The forthcoming revolution of DC electrical infrastructure for commercial and residential buildings

Off-Grid

  • Watch Cal Poly team build DC powered community center and ice production center in Ghana (see Marshall lighting fixture in action at 2:14 of video).
  • In just five years Papua New Guinea has achieved dramatic growth to become a leader among developing countries in the use of off-grid solar products.
  • PNG has one of the highest rates of use of off-grid solar lighting in the developing world.

DC Backup & Grid Resiliency

  • The bipartisan infrastructure bill — which mentions microgrids five times — would pump billions of dollars into the US grid, partly to bolster reliability and resilience.
  • 44% of respondents have considered investing in microgrids for their facility.
  • 54% of those respondents those who expressed interests in microgrids did so because of critical operations that require uninterrupted power supply.
  • The utility-scale battery located outside of Houston will connect to the same grid that faltered in February’s freeze.
  • A battery that size could power about 20,000 homes on a hot summer day.
  • The Department of Homeland Security issued a report on China’s ability to conduct an electromagnetic pulse (EMP) attack on the United States.
