Steel is the world's most popular construction material because of its unique combination of durability, workability, and cost. It's an iron alloy that contains between 0.2 and 2 percent carbon by weight.According to the World Steel Association, in 2016 global crude steel production reached a high of 1, 628.5 million tonnes. Of this, approximately three-quarters were produced using BOS plants, while EAF facilities accounted for the remaining quarter.Some of the largest steel producing countries are China, Japan, US, and India. China accounts for roughly 50 percent of this production.The world's largest steel producers include ArcelorMittal, Hebei Steel Group, Baosteel, POSCO and Nippon Steel.

Modern steelmaking can be broken down into six steps:1. Ironmaking: In the first step, the raw inputs iron ore, coke, and lime are melted in a blast furnace.The resulting molten iron, also referred to as 'hot metal, ' still contains 4-4.5% carbon and other impurities that make it brittle.2. Primary Steelmaking: There are two primary steelmaking methods: BOS (Basic Oxygen Furnace) and the more modern EAF (Electric Arc Furnace) methods. BOS methods add recycled scrap steel to the molten iron in a converter.

Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. Modern methods, however, are still based the same premise as the original Bessemer Process, which uses oxygen to lower the carbon content in iron.Today, steel production makes use of both recycled materials, as well as the traditional raw materials, such as iron ore, coal, and limestone. Two processes; basic oxygen steelmaking (BOS) and electric arc furnaces (EAF) account for virtually all steel production.

Delhi’s Solar Revolution: Powering Homes, Saving Planet As Delhi grows vertically and population density increases, so does the strain on its energy grid. Air conditioners hum louder in the summer, electric vehicles are becoming the norm, and power outages—though fewer—still pinch in peak seasons. Amid this rising energy demand, a quiet but powerful revolution is taking place on rooftops: solar plates are emerging as the go-to solution for Delhiites who want clean, reliable, and affordable electricity. What Are Solar Plates, and Why Are They Trending in Delhi? Solar plates , or solar panels, capture sunlight and convert it into electricity using photovoltaic (PV) cells. While the technology has been around for decades, several factors are now making it more appealing to Delhi’s residents: Affordable installation with falling prices State and central government subsidies Delhi's harsh summers and long sunny days Growing environmental consciousness Whether you're living in Lajpat Nagar, running a business in Pitampura, or managing a school in Noida, solar panels can drastically lower your monthly electricity bills while making your space more sustainable. Why Solar Makes Sense in Delhi – Now More Than Ever 🌞 Excellent Solar Potential Delhi receives an average solar radiation of 5.5 kWh/m²/day , which is ideal for power generation. Even in winter months, there's sufficient sunlight to generate power for most residential needs. 💸 Energy Cost Savings Electricity tariffs in Delhi range from ₹4 to ₹8 per unit depending on consumption slabs. A typical household with a 3kW solar system can save up to ₹2,000–₹4,000 per month, with total payback in just 4–6 years . 🏠 Increase Property Value A solar-equipped home is not just energy-efficient but also more attractive to environmentally conscious buyers. Think of it as an investment in your home’s equity and future marketability. 📉 Fall in Solar Equipment Prices Compared to five years ago, the cost of installing a rooftop solar system has dropped by almost 30–40% . Better technology, higher efficiency panels, and local manufacturing have made solar more accessible. Delhi’s Solar Policies: What You Should Know Under the Delhi Solar Policy , there are various incentives and frameworks to promote solar adoption: Subsidy of up to 40% for residential rooftop solar systems up to 3kW capacity Net metering that allows consumers to export excess power and get credit Zero investment models via RESCO (Renewable Energy Service Company) for schools, societies, and commercial users You can apply for subsidies and net metering directly through your electricity provider (BSES Rajdhani, BSES Yamuna, or TPDDL), or work with an MNRE-approved installer who handles paperwork for you. Real-World Applications in Delhi 🏢 Housing Societies Many RWAs in South Delhi and Dwarka are turning common rooftops into power hubs. Shared solar systems reduce common area bills and maintenance charges. 🛒 Shops and Small Businesses From boutique stores in Hauz Khas to salons in Karol Bagh, small enterprises are adopting solar to stabilize operational costs and avoid outages. 🏫 Schools and Colleges Institutions like DPS and Amity have installed large-capacity solar panels to power classrooms and labs, reducing carbon footprint and costs. 🕌 Temples and NGOs Non-profits and religious institutions are going green too, using solar power for fans, lights, and water heating systems. How to Get Started: Steps to Solar in Delhi Assess your energy usage Look at your last 6–12 months of electricity bills. Site inspection An installer will inspect your roof for sunlight exposure, angle, and structure. Get a quote and choose your system Based on budget and energy needs – on-grid, off-grid, or hybrid. Apply for subsidy and net metering Usually handled by your vendor. Installation and activation Takes 1–2 weeks, depending on system size and approvals.

Harnessing the Sun: Why Solar Plates Are Booming in Delhi With rising electricity costs and increasing environmental concerns, Delhi is witnessing a surge i the adoption of solar plates (solar panels) across homes, businesses, and institutions. The city, blessed with ample sunlight throughout the year, is an ideal candidate for solar energy. If you're in Delhi and considering switching to solar, now is the perfect time. Why Go Solar in Delhi? 1. Abundant Sunlight Delhi gets around 300 sunny days a year, making solar energy a highly reliable power source. Solar panels can work even on cloudy days, but maximum efficiency is achieved with bright sunlight – and Delhi has plenty of it. 2. Cut Down Electricity Bills The biggest benefit of solar plates is the significant reduction in electricity bills. Residential consumers using rooftop solar can save up to 80% on their monthly bills. Over 5–6 years, the savings can cover the installation cost, and after that, it’s free power for the next 15–20 years. 3. Government Subsidy in Delhi Under the Rooftop Solar Programme by MNRE (Ministry of New and Renewable Energy) and Delhi’s local initiatives, residential consumers can get up to 40% subsidy for systems up to 3kW. This significantly reduces the upfront investment. For example: 1kW system (suitable for a small household): ₹60,000–₹70,000 After subsidy: ~₹36,000–₹42,000 For larger systems, the subsidy percentage reduces, but total savings increase as well. 4. Net Metering Facility Delhi's DISCOMs (like BSES, TPDDL) offer net metering, allowing you to export excess solar power to the grid and receive credits on your bill. This means your meter can literally run backward when you're producing more than you use. 5. Environment-Friendly Energy Using solar plates helps reduce your carbon footprint. A 1kW solar system can offset approximately 1.5 tons of CO2 emissions per year — equivalent to planting 15–20 trees annually. In a city like Delhi, where air pollution is a serious concern, going solar is a direct step toward cleaner air. Types of Solar Systems Available On-Grid System Connected to the electricity grid Most common and cost-effective Supports net metering Works only when grid power is available Off-Grid System Includes battery backup Useful for remote or power-cut-prone areas Higher initial cost due to batteries Hybrid System Combines on-grid and off-grid features Offers flexibility and reliability How to Choose the Right System? For small homes: A 1kW to 2kW on-grid system is sufficient. For medium to large homes: Go for 3kW to 5kW. For commercial buildings: Systems from 10kW to 100kW+ depending on usage. Professional solar consultants in Delhi can perform a site survey, check your roof’s strength, shade patterns, and recommend the right system capacity
