Renewables Provided 17.6% of Electricity Generation in the U.S. in 2018

Overall, renewable generation in the U.S. provided a new record of 742 million MWh of electricity in 2018, nearly double the 382 million MWh produced in 2008. This is according to data recently released by the U.S. Energy Information Administration. In fact, renewables provided 17.6% of electricity generation in the U.S. in 2018.

However, conventional hydroelectric capacity has remained relatively unchanged, increasing by only 2% since 2008. Changes in hydroelectric generation year-over-year typically reflect changes in precipitation and drought conditions. Between 2008 and 2018, annual U.S. hydroelectric generation was as low as 249 million MWh and as high as 319 million MWh, with hydroelectric generation in 2018 totaling 292 million MWh.

Nearly 90% of the increase in U.S. renewable electricity between 2008 and 2018 came from wind and solar generation. Wind generation rose from 55 million MWh in 2008 to 275 million MWh in 2018 (6.5% of total electricity generation), exceeded only by conventional hydroelectric at 292 million MWh (6.9% of total generation).

U.S. solar generation has increased from 2 million MWh in 2008 to 96 million MWh in 2018. Solar generation accounted for 2.3% of electricity generation in 2018. In 2018, 69% of solar generation, or 67 million MWh, was utility-scale solar.

Increases in U.S. wind and solar generation are driven largely by capacity additions. In 2008, the U.S. had 25 GW of wind generating capacity. By the end of 2018, 94 GW of wind generating capacity was operating on the electric grid. Almost all of this capacity is onshore; one offshore wind plant, located on Block Island, off the coast of Rhode Island, has a capacity of 30 MW. Similarly, installed solar capacity grew from an estimated less than 1 GW in 2008 to 51 GW in 2018. In 2018, 1.8 GW of this solar capacity was solar thermal, 30 GW was utility-scale solar photovoltaics (PV), and the remaining 20 GW was small-scale solar PV.

GADS OS on the Desktop

GADS OS is a desktop application.  Ever wonder why?  Are we the only ones who have desktop applications?

Millions of developers develop and maintain Windows Forms (desktop) applications. According to Microsoft, over two million developers actively work on Windows Forms applications every month, and we're some of them.

The fact is, some applications still can’t be done well in a browser. In fact, we have a whole team at the GADS Open Source Project that specializes in high-performance desktop work and does quite well because they can do some amazing things that can’t be achieved with other technologies. We’ve been taking advantage of the Windows built-in .NET Framework to write libraries for our GADS OS desktop apps for a while now, and the apps themselves have required the full framework, installers, and everything that goes with fat client, native desktop applications.

The problem is that Web apps are browser-based, not browser agnostic.  A browser-agnostic Web application should work on Edge, Firefox, Chrome, Internet Explorer, Opera or any other browser equally well, but that's not always the case or possible.  All the features and capabilities that make today's browsers so powerful and complex also cause some problems for users.

Issues such as plug-ins, security settings and version requirements mean that managing browsers can be a lot of work. With large enterprise line-of-business applications like GADS data reporting and analysis, the problem of browser compatibility compounds.

GADS OS Software Now Requires .NET Framework 4.6.1 or Higher

All good things must come to an end, even Windows 7. After January 14, 2020, Microsoft will no longer provide security updates or support for PCs running Windows 7. But you can keep the good times rolling by moving to Windows 10.

The GADS OS software versions prior to 2019 required .NET Framework 4.5.2 or higher. The release of .NET Framework 4.5.2 was announced on 5 May 2014.

Beginning with versions 19.x.x.x, the GADS OS software will require .NET Framework 4.6.1 or higher.  The release of .NET Framework 4.6.1 was announced on 30 November 2015. This version requires Windows 7 SP1 or later.
