Public-sector involvement in information provision to farmers has long been a cornerstone of agricultural development strategies, with large proven benefits to agricultural output in both rich and poor countries (Birkhaeuser et al. 1991; Alston 2000). These strategies can involve educating farmers about the availability of new technology and how to use it, providing information on improved farm management techniques such as optimal input use, or providing forecast information about likely short- or longer-run shifts in climate. Including farmers in research design and implementation can also be an important means toward successful technology adoption. For example, adoption of new wheat varieties and no-till management in South Asia has been greatly accelerated through participatory research trials conducted in farmers' fields, where farmers' can see first-hand the benefits of new seeds or techniques (Ortiz-Ferrara et al. 2007).

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
