it spends a matching dollar to install new solar on other nonprofits, which get free electricity from those installations.

#Biofuels: plant the right crop in the right place (Nanowerk News) Corn, wheat and rapeseed can be used to produce biofuels, such as bioethanol and biodiesel.
According to recent findings by environmental scientists at Radboud University, the location of the agricultural lands used to grow these biofuel crops has a major impact on the greenhouse gas emission they ultimately produce.
The study that arrived at this conclusion is due to be published By nature Climate change("Greenhouse gas payback times for crop-based biofuels".
"This figure shows the duration of the payback times for greenhouse gases produced by corn-based bioethanol per intensively farmed crop location,
i e. where fertilizers and irrigation are used. While intensive crop farming results in greater greenhouse gas emission, it also increases the yields of crops used to produce biofuels and,
ultimately, reduces emission levels. To increase production of biofuels from crops, such as corn and wheat,
natural areas need to make way for agricultural land. The initial result of this is an increase in greenhouse gas emission.
Pieter Elshout and fellow environmental scientists at Radboud University have demonstrated how long it takes for the advantages that biofuels offer over fossil fuels to earn a return on this initial emission On the global scale,
This figure shows the duration of the payback times for greenhouse gases produced by corn-based bioethanol,

By 2020, the EU aims to have 10 per cent of the transport fuel of every EU country come from renewable sources such as biofuels.
Fuel suppliers are required also to reduce the greenhouse gas intensity of the EU fuel mix by 6 per cent by 2020 in comparison to 2010.
At present, biodiesel is produced by combining fats and oils with methanol, which is derived usually from fossil fuels.
which could then be used as a starting reactant to create more biodiesel. To achieve this, the researchers reacted glycerol with water,
the researchers estimate up to a 10 per cent increase in biodiesel production, which they claim would be very helpful to industry at this point in time.
