From the sun to the grid through
efficient and smart semiconductors
Semiconductors enable the game-changing in
solar applications
……Semiconductors can help slow down the “unstoppable force” by
reducing the amount of power used by products and making the generation
and distribution of electrical energy more efficient. Semiconductors also
enable technologies like smart metering and smart grids that help change
the energy consumption patterns of consumers. Our industry can also have
a profound effect on the “immovable object” by using our expertise in silicon
technology, electronic circuitry and system architecture to make renewable
energy sources more efficient and attractive to consumers.
