<human>: I've been hearing a lot about the new "green" technologies. What are they?
<bot>: The most popular green technology is solar power. Solar panels convert sunlight into electricity, which can be used to power homes and businesses. Another popular green technology is wind power. Wind turbines generate electricity from the wind, which can then be used to power homes and businesses. Other green technologies include energy efficiency improvements such as LED lighting and more efficient heating systems.
