Can Build-Your-Own Solar System Help The US Reach Biden's Climate Goals?
Fossil fuels produce 83% of the world's energy and 73% of the world's greenhouse gases. How best can renewables like solar and wind change this picture?
Solar and wind energy are already often the lowest cost producers of electricity and when they offset fossil fuels they help to cut down our greenhouse gas emissions. Large companies – think Google, Apple, Ikea and Walmart etc.
Odd Martian meteorites traced back to largest volcanic structure in the solar system
About a million years ago, an asteroid smacked into the normally tranquil surface of Mars. The impact released a fountain of debris, and some of the rocky fragments pierced the sky, escaping the planet's gravity to journey through the dark.
Some of the rocks eventually found their way to Earth and survived the plunge through our planet's atmosphere to thud into the surface–including a hefty 15-pound shard that crashed into Morocco in 2011.
Alien Worlds Hold Minerals Like Nothing in Our Solar System, Scientists Say
They are small, dim, and distant, which means that we don't have a lot of detailed information about what they're made of. This is especially true for rocky exoplanets, like Earth, Venus , and Mars , of which we can't currently see the surfaces.
There is, however, one way we can peer into the guts of rocky worlds – and it suggests that some of the minerals they're made of are nothing like the minerals in the Solar System. So alien are these minerals, in fact, that scientists had to invent new terms to classify them.
Our Solar System's Planetary Orbits Are Ultimately Chaotic, Says French Astronomer

Although the term itself immediately conjures the sort of alchemy at the heart of the best sci-fi fantasy, celestial mechanics —- the numerical nuts and bolts of how planetary bodies move, orbit and rotate over cosmic time —- is as old as astronomy itself.
A look at the Oort cloud, on the very edge of the solar system
Every system needs a boundary, and the Solar System is no different. Although we haven’t been able to physically reach and see it, we have a theory about what this edge looks like. And its name is the Oort cloud.
Ask anyone on the street where the Solar System ends, and they’re likely to mention Pluto. To a certain extent, it wouldn’t be wrong; Pluto really is the farthest planet / dwarf planet from the Sun.

The mere thought can send you down an existential rabbit hole. But I like to look at the universe and consider all of the possibilities just awaiting discovery.
Astronomers have yet to find a solar system quite like ours. And of the thousands of known exoplanets, none quite match up with the planets in our cosmic backyard. But scientists have only just begun to scratch the surface of these planets outside the solar system.
Average Cost of Solar Panels in Arizona: What to Expect (2022) - EcoWatch
Anyone who has spent time in the southwestern U.S., particularly in the deserts of Arizona, would find it no surprise that the region has some of the best natural solar resources in the country.
From reduced energy bills to shrunken carbon footprints, there are many benefits of going solar . Regardless, for most homeowners, making the switch comes down to one key question: How much do solar panels cost in Arizona?
