How Do Solar Lamps Impact the Environment?
Solar lamps can reduce deforestation – often times timber and plant resources are depleted for lighting. For example, in northern Nicaragua a plant known as Ocote is used for lighting and in some villages has been completely depleted. Solar lamps can reduce air pollution by displacing kerosene and gas burning lights. Solar lamps can also reduce the amount of battery waste by providing rechargeable batteries. However, solar lamps do use plastic and batteries, which may require proper disposal after its lifetime is complete.

What Does Bright New Ideas do to Reduce Battery Waste?

To reduce waste and keep an eye on environmental concerns, batteries may be tracked by serial number as well and a given family may return their own battery upon the end of use (after approximately two years) for proper disposal, receiving money back for their return.

How Does Bright New Ideas Calculate its Reduced Carbon Emissions?

Bright New Ideas uses a formula based upon the number and time and number lamps have been in existence, the known amount of kerosene or bio-fuel-based lighting these lamps have displaced, and a coefficient corresponding to the amount of pounds of CO2 put into the air by burning a certain volume of bio-fuel of a given type. These coefficients are found on the US Department of Energy Website.
