Moreover they hold collectively the greatest potential for addressing the climate crisis in a sustainable, decentralised and costCost: The consumption of resources such as labour time, capital, materials, fuels, etc. as the consequence of an action. In economics, all resources are valued at their opportunity cost, which is the value of the most valuable alternative use of the resources. Costs are defi ned in a variety of ...-effective way.

Despite the world’s recent annual average of 1.5% increase in energy consumption, and an average 3% growth in Gross Domestic Product, carbon dioxideCarbon dioxide (CO2) is emitted in several ways. Naturally through the carbon cycle and through human activities like the burning of fossil fuels. These human activities have increased CO2 concentrations in the atmosphere since the beginning of the industrial revolution and these high ... (CO2) emissionsEmissions of greenhouse gases, greenhouse gas precursors, and aerosols associated with human activities, including the burning of fossil fuels, deforestation, land-use changes, livestock, fertilisation, etc. (IPCC) in 2014 were unchanged from 2013 levels. For the first time in four decades, the world economy grew without a parallel rise in CO2 emissions. This landmark “decoupling” was due—in large part—to the increased use of renewable resources, and efforts to promote more sustainable growth through increased use of energy efficiencyUsing less energy/electricity to perform the same function.

It can be a natural phenomena and and has occurred on Earth even before people inhabited it. Quite different is a current situation that is also referred to as climate change, anthropogenic climate change, or ....

The numbers speak for themselves. By the end of 2014, renewables contributed 19.1% to the global final energy consumption and supplied 22.8% of the world’s electricityElectricity generation includes all technologies that turn some form of energy into useful electric energy. Electricity is a form of energy that has magnetic, radiant and chemical effects. Electric current is created by a flow of electrons..  Over the course of the year, renewables represented 59% of net additions to global power capacity, clearly showing that a transition to renewables is well underway in the electricity sector.  Nevertheless, this transition must be accelerated across all energy sectors. In 2014, renewables contributed only 8% to the heating and cooling sector.  And much more action is needed to decarbonise the transport sector.

It is evident that renewables are part of the solution agenda to reaching the 1.5C objective. We have the technological solutions to address this challenge.  Morally we have no excuse not to commit to an energy transition that moves us towards 100 % renewable energy and energy efficiency, and thereby ensuring energy accessEnergy access represents a crucial yet often overlooked dimension to the issue of poverty. Relatively small amounts of energy can satisfy the basic needs of rural populations and have a dramatic impact on quality of life. Despite this, approximately 3 billion people , half the worlds population, ... for all.

Renewables are cost-completive; the renewables trainRail transport is a means of conveyance of passengers and goods, by way of wheeled vehicles running on rails. It is also commonly referred to as train transport. In contrast to road transport, where vehicles merely run on a prepared surface, rail vehicles are also directionally guided by the ... has left the station.  An ambitious agreement coming out of the Paris talks would do much to help accelerate this transition.
