Arent Renewables expensive?
With the exception of large hydropower plants, most renewable energy is not as economic as fossil fuel generation although landfill gas and onshore wind in favorable locations are becoming reasonably close. However, there is significant scope for cost reduction. For example, wind costs have declined by over 80 per cent in the last two decades, with room for further improvement. Many renewable technologies are expected to become cost-competitive with fossil fuels in the next 10 to 20 years, especially as fossil fuel prices rise as reserves begin to decline. Renewable energys competitiveness will also be enhanced by policies that begin to incorporate the environmental and social costs of using fossil fuels, which are not currently reflected in their price (such as global warming, acid rain, air pollution and its effect on human health, etc).
