RENEWABLE ENERGY: THE CLEAN FACTS

Wind and sun oriented are controlling a perfect energy transformation. This is what you need to think about renewables and how you can help have an effect at home.
Solar Energy
Solar Energy
Sun powered, or photovoltaic (PV), cells are produced using silicon or different materials that change daylight straightforwardly into power. Disseminated galaxies create power locally for homes and organizations, either through roof boards or local area projects that power whole areas. Sun based ranches can produce power for a large number of homes, utilizing mirrors to think daylight across sections of land of sunlight based cells. Drifting sun based homesteads or "floatovoltaics" can be a successful utilization of wastewater offices and waterways that aren't naturally touchy. Sunlight based supplies somewhat more than 1% of U.S. power age. However, almost 33% of all new creating limit came from sun powered in 2017, second just to petroleum gas. Sun oriented energy frameworks don't create air toxins or ozone depleting substances, and as long as they are dependably sited, most sunlight based boards have not many natural effects past the assembling interaction.
Wind Energy
Wind Energy
We've made considerable progress from older style wind plants. Today, turbines as tall as high rises with turbines almost as wide in measurement prepare for action all throughout the planet. Wind energy turns a turbine's sharp edges, which takes care of an electric generator and produces power. Wind, which represents somewhat more than 6% of U.S. age, has become the least expensive fuel source in numerous pieces of the country. Top breeze power states incorporate California, Texas, Oklahoma, Kansas, and Iowa, however turbines can be put anyplace with high wind rates like ridges and open fields or even seaward in untamed water.
Hydroelectric Power
Hydroelectric Power
Hydropower is the biggest sustainable power hotspot for power in the United States, however wind energy is before long expected to assume control over the lead. Hydropower depends on water commonly quick water in an enormous waterway or quickly diving water from a high point and converts the power of that water into power by turning a generator's turbine sharp edges. Broadly and globally, huge hydroelectric plants or super dams are frequently viewed as nonrenewable energy. Uber dams redirect and decrease common streams, confining access for creature and human populaces that depend on waterways. Little hydroelectric plants (an introduced limit underneath around 40 megawatts), painstakingly oversaw, don't will in general reason as much natural harm, as they redirect just a negligible portion of stream.
Biomass Energy
Biomass Energy
Biomass is natural material that comes from plants and creatures, and incorporates crops, squander wood, and trees. At the point when biomass is singed, the compound energy is delivered as warmth and can create power with a steam turbine. Biomass is frequently erroneously portrayed as a spotless, inexhaustible fuel and a greener choice to coal and other non-renewable energy sources for creating power. In any case, late science shows that numerous types of biomass particularly from backwoods produce higher fossil fuel byproducts than petroleum derivatives. There are additionally unfortunate results for biodiversity. All things considered, a few types of biomass energy could fill in as a low-carbon alternative under the right conditions. For instance, sawdust and chips from sawmills that would some way or another rapidly deteriorate and discharge carbon can be a low-carbon fuel source.
Geothermal Energy
Geothermal Energy
In the event that you've at any point loose in an underground aquifer, you've utilized geothermal energy. The world's center is probably just about as warm as the sun's surface, because of the sluggish rot of radioactive particles in rocks at the focal point of the planet. Penetrating profound wells carries hot underground water to the surface as an aqueous asset, which is then siphoned through a turbine to make power. Geothermal plants commonly have low emanations on the off chance that they siphon the steam and water they use once more into the supply. There are approaches to make geothermal plants where there are not underground supplies, but rather there are worries that they may build the danger of a seismic tremor in regions previously viewed as topographical problem areas.
Nuclear
Nuclear
Atomic force, the utilization of supported atomic parting to create warmth and power, contributes almost 20% of the power produced in America. The United States has utilized atomic force for over 60 years to create solid, low-carbon energy and to help public protection exercises. The Energy Department's Office of Nuclear Energy's essential mission is to progress atomic force as an asset fit for making significant commitments in gathering our country's energy supply, ecological, and energy security needs. By zeroing in on the improvement of cutting edge atomic advances, NE upholds the Administration's objectives of giving homegrown wellsprings of secure energy, lessening ozone depleting substances, and upgrading public safety. Atomic force stays a significant piece of our country's energy portfolio, as we endeavor to diminish fossil fuel byproducts and address the danger of worldwide environmental change.
Bioenergy
Bioenergy
Biomass is a natural environmentally friendly power source that incorporates materials like farming and timberland buildups, energy yields, and green growth. Researchers and architects at the Energy Department and National Laboratories are discovering new, more productive approaches to change over biomass into biofuels that can replace ordinary fills like gas, diesel, and fly fuel. Bioenergy can help guarantee a monetarily strong and secure future while decreasing natural effects through: 1.Developing moderate homegrown fills and co-items 2. Propelling clean fuel sources 3.Generating homegrown responsibilities to help the development of the U.S. bioeconomy. Innovative work to change inexhaustible carbon and waste assets into feedstocks for transformation to biofuels, bioproducts, and bio power will reasonably grow biomass asset potential in the United States.
Hydrogen and Fuel Cells
Hydrogen and Fuel Cells
The Hydrogen and Fuel Cell Technologies Office (HFTO) centers around exploration, advancement, and exhibit of hydrogen and power module advances across various areas empowering development, a solid homegrown economy, and a perfect, evenhanded energy future. Hydrogen is the least difficult and most bountiful component known to man. It is found inside water, petroleum derivatives, and all living matter, yet it seldom exists as a gas on Earth—it should be isolated from different components. There are different homegrown assets that can be utilized to deliver hydrogen, including renewables (wind, sun oriented, hydropower, biomass, and geothermal energy), atomic force, and petroleum products (like flammable gas and coal – with carbon catch and sequestration). The U.S. at present creates in excess of 10 million metric huge loads of hydrogen each year, around one-seventh of the worldwide inventory.

‘Say what we do, do what we say’: Behind the scenes on Nextracker’s ISO 9001:2015 certification journey

The International Organization for Standardization, better known by its acronym ISO, is an independent, non-governmental international organization with a membership of 165 national standards bodies.

The International Organization for Standardization, better known by its acronym ISO, is an independent, non-governmental international organization with a membership of 165 national standards bodies. The ISO family of thousands of standards covers pretty much all aspects of technology and manufacturing. One of the more familiar of those myriad families of standards is ISO 9000 and ISO 9001 in particular, which focuses on quality management systems (QMS). Getting ISO’ed is a big deal, and I’m proud to have helped lead the charge at Nextracker to achieve certification for ISO 9001:2015.

As I said in our press release about earning the ISO certification, every Nextracker solar tracker is designed and built to the highest quality standards. Our ISO 9001:2015 accreditation is confirmation of our demonstrated and ongoing commitment to reliability, quality assurance, the environment, and safety. Although that quote puts a nice bow on things, it doesn’t do justice to the heavy lift that was involved by my teammates across the Nextracker organization to get to the ISO finish line.

After kicking around the idea for a long time and knowing many of our biggest customers were pushing for us to get ISO’ed, we officially began the process in November 2020. We knew we were pretty far down the road to compliance and meeting the needs of our customers with our existing QMS, but we needed fresh independent eyes to assess our efforts and to make sure everything we were doing was best in class.

In December, we conducted “gap assessments” in our own systems and found some gaps associated with certain specific requirements of ISO 9001:2015, such as risk assessment and risk mitigation processes that we did have in place but didn’t have properly documented. One of the keys to the ISO process is “say what you do, do what you say,” which means having everything documented for repeatability and reproducibility and following those documented processes closely. It’s also important to have precise and clear wording in your documentation that aligns with the ISO specifications.

The gap-closing process ran through the first few months of 2021, after which we went right into the all-important audits. The first stage of the audit took a few days, but the second stage was a grueling 7-day stretch of deep-dive, fully focused audits. Our auditors were SGS, the world’s leading testing, inspection, and certification company.

During the audit, nearly all aspects of our business systems were closely scrutinized. Key groups within the company had to document every process involved in what they do. The auditors went through each and every one of those processes we’d written down, to understand what we do, and we had to give examples to prove we do what say. It was a monumental cross-functional team effort. The entire ISO process usually takes a year or so, but we completed it in about 6 months.

While much attention is paid to the quality management part of it, the audit process was more than just a quality review. As noted, it also focused on the broader business management system and customer relations. The questions we faced included:

  • Are you able to meet the needs of the customer?
  • Are you appropriately hearing their voice and then making products that conform to their needs?
  • Can you plan to meet your demand forecast?
  • Do you have a strong product development system?
  • Do you have a robust supply chain?
  • Can you accommodate logistical changes or changes in tariffs that could be occurring from country to country?
  • Do you conform to the requirements of local government rules and regulations?
  • Have you anticipated the risks and have mitigations in place to deal with them?

Nextracker has grown phenomenally over the past few years – but with growth comes risk. If you don’t have a scalable process, a repeatable process, then you can find yourself in trouble. Getting ISO certified is confirmation that we have the appropriate procedures, documentation, measurement systems and corrective systems in place—a real key to achieving scalability. The other part of 9001 is the customer connection because a company can’t thrive and expand without hearing what the customer has to say and responding to what the customer needs. Believe me, we listen very closely to what our customers are telling us and have the documented processes to prove it.

Achieving ISO 9001 is by no means an end in itself, it is just the beginning: it provides the solid foundation and continuous improvement mindset on which we’re building our efforts to obtain additional ISO and other certifications. We are already working on two other ISOs–ISO 14001:2015 (for environmental management) and ISO 45001 (for occupational health and safety management)–and expect to have the audits completed and the certifications signed off before the end of the year. This ISO journey is one of the keys to our continuing success as we scale toward our first 100 GW of shipments and installed capacity.
