From Pope Benedict XVI’s encyclical Caritas in Veritate (2009):
Questions linked to the care and preservation of the environment today need to give due consideration to the energy problem. The fact that some States, power groups and companies hoard non-renewable energy resources represents a grave obstacle to development in poor countries. Those countries lack the economic means either to gain access to existing sources of non-renewable energy or to finance research into new alternatives. The stockpiling of natural resources, which in many cases are found in the poor countries themselves, gives rise to exploitation and frequent conflicts between and within nations. These conflicts are often fought on the soil of those same countries, with a heavy toll of death, destruction and further decay. The international community has an urgent duty to find institutional means of regulating the exploitation of non-renewable resources, involving poor countries in the process, in order to plan together for the future.
On this front too, there is a pressing moral need for renewed solidarity, especially in relationships between developing countries and those that are highly industrialized.118 The technologically advanced societies can and must lower their domestic energy consumption, either through an evolution in manufacturing methods or through greater ecological sensitivity among their citizens. It should be added that at present it is possible to achieve improved energy efficiency while at the same time encouraging research into alternative forms of energy. What is also needed, though, is a worldwide redistribution of energy resources, so that countries lacking those resources can have access to them. The fate of those countries cannot be left in the hands of whoever is first to claim the spoils, or whoever is able to prevail over the rest. Here we are dealing with major issues; if they are to be faced adequately, then everyone must responsibly recognize the impact they will have on future generations, particularly on the many young people in the poorer nations, who “ask to assume their active part in the construction of a better world.”119
