To accelerate the inevitable transition from fossil fuels to more practical and sustainable cleaner fuels, we first need to fathom them, who is developing and promoting them, and ultimately where we can buy/invest in them.
Supporting the space program is probably the simplest of accelerating the transition to cleaner energy sources, regardless of whether or even otherwise you care about inter-planetary exploration, because by developing the technologies to reach other worlds, we are developing the technologies discovered stay on this environment. Like all space programs, safe and efficient energy generation, storage, and control is one of NASA's most significant barriers that it faces toward progress. Naturally, NASA-related projects lead the field when it comes to making solar power more practical.
For example, there can be a photovoltaic cell paint, called plasmonic-enhanced organic photovoltaic material, that is being developed to generate power 'on the sly', with no bulky solar panels to install or maintain: just paint it anywhere and connect your device. Less power efficient, perhaps, than rooftop solar panels aimed always at the sun, however this paint will be much cheaper, less obtrusive, and won't contain dangerous cadmium alloys, as many traditional solar power systems do, therefore.
Integrating solar panels into our daily lives, and investing in wind and water power among other options, is paramount to worldwide progress.
To accelerate this transition to cleaner fuels, ought to first actively educate ourselves about the options, just to integrate them into our daily lives:
Examples of progress: Who still uses a replaceable-battery-powered calculator rather than a solar-powered one? How many street crosswalks or road construction projects in your community are heralded with a solar-powered flashing sign or light? How many neighbors use solar-powered flood lights or accent lights, instead of direct current lights, to light their house or highlight their landscaping or walkways?
The transition from fossil fuels to cleaner fuels is occurring, but to accelerate it we must invest in it personally, tolerate some growing pains, and spread the phrases. Like the Japanese principle of continuous quality improvement, kaizen--taking tiny steps all the time toward the goal--we, too, will increase the use of cleaner fuels. However, actively educating ourselves and investing and lobbying for their use: that is the way you can take giant steps in accelerating this shift to cleaner fuels and thereby reduce the usage of fossil fuels.
