Fig. 4.12 Light use efficiency (LUE) during light flecks as a function of light fleck duration (log scale on the x-axis) in induced (closed symbols) and uninduced (open symbols) leaves of three tropical rain forest understory shrub species. (After data of Valladares et al. 1997)

Fig. 4.13 Efficiency of the utilization of 5-s light flecks (PPFD = 500 ^mol photons m-2s-1) on a background irradiance of PPFD varied between 0 and 10^mol photons m-2s-1 given for 60 s after each light fleck. In each case, leaves had been conditioned to reach a steady-state CO2 assimilation at 500 ^mol photons m-2c-1 and Pearcy 1988b)

Renewable Energy 101

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.
