Use solar-powered pathway lights
Light for safety and inconvenience without the power bills
A solar-powered outdoor light incorporates a small photovoltaic(PV) Generation of electricity directly from sunlight. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow. (PVPhotovoltaics. Generation of electricity directly from sunlight.

The light goes on automatically at dusk and switches off during the day. No wiring or switching is required, which can make these energy-independent fixtures very cost effective in some applications. Plus, they use no utility-company electricity. One drawback is that solar fixtures generally use fairly small lamps that don't throw much light.
