What do people use for winnowing? Give the words in your language, if you know them. Yes, I have seen many women winnowing grains in villages. It is is generally known as phatkna, pichorna or anaj parchana in Hindi. People use chaaj winnowing fan for winnowing. Note: This answer just provides a framework or clue to students. They are suggested to write it in their own words based on their own experience.
The poet says that the wind god winnows the weak crumbling houses, doors, rafters, wood, bodies, lives and hearts, and crushes them all. To make friends with wind we need to build strong homes with firm doors. We should also practice to make our bodies and hearts stronger. In the last four lines, the poet inspires us to be determined and face all the hardships or obstacles coming in life courageously. And is now available for your free and fast download.

Cost reductions in renewables and advances in digital technologies are opening huge opportunities for energy transitions, while creating some new energy security dilemmas.
Wind and solar PV provide more than half of the additional electricity generation to in the Stated Policies Scenario and almost all the growth in the Sustainable Development Scenario. Policy makers and regulators will have to move fast to keep up with the pace of technological change and the rising need for flexible operation of power systems. Issues such as the market design for storage, the interface between electric vehicles and the grid, and data privacy all have the potential to expose consumers to new risks.
Africa — the special focus of WEO — is increasingly influential for global energy trends. The big open question for Africa remains the speed at which solar PV will grow. Solar PV would provide the cheapest source of electricity for many of the million people across Africa without electricity access today. The faltering momentum behind global energy efficiency improvements is cause for deep concern.
It comes against a backdrop of rising needs for heating, cooling, lighting, mobility and other energy services. Improvements in the energy intensity of the global economy the amount of energy used per unit of economic activity are slowing: the 1. This reflects a relative lack of new energy efficiency policies and of efforts to tighten existing measures. A sharp pick-up in efficiency improvements is the single most important element that brings the world towards the Sustainable Development Scenario.
This includes efforts to promote the efficient design, use and recycling of materials such as steel, aluminium, cement and plastics. Innovative approaches also include the use of digital tools to shift electricity demand to cheaper and less emissions-intensive hours of the day, reducing electricity bills for consumers and helping with system balancing, while also helping to reduce emissions.
Coal is the incumbent in most developing Asian countries: new investment decisions in coal-using infrastructure have slowed sharply, but the large stock of existing coal-using power plants and factories and the GW of capacity under construction worldwide , provides coal with considerable staying power in the Stated Policies Scenario. Developing countries in Asia account for over half of the global growth in generation from renewables. Demand for natural gas has been growing fast as a fuel for industry and in China for residential consumers, spurring a worldwide wave of investment in new LNG supply and pipeline connections.
In the Stated Policies Scenario, global growth in oil demand slows markedly post before flattening out in the s. Oil demand for long-distance freight, shipping and aviation, and petrochemicals continues to grow. But its use in passenger cars peaks in the late s due to fuel efficiency improvements and fuel switching, mainly to electricity.
Lower battery costs are an important part of the story: electric cars in some major markets soon become cost-competitive, on a total-cost-of-ownership basis, with conventional cars. Consumer preferences for SUVs could offset the benefits from electric cars. The growing appetite among consumers for bigger and heavier cars SUVs is already adding extra barrels to global oil consumption.
If the popularity of SUVs continues to rise in line with recent trends, this could add another 2 million barrels per day to our projection for oil demand. Electricity use grows at more than double the pace of overall energy demand in the Stated Policies Scenario, confirming its place at the heart of modern economies.
Growth in electricity use in the Stated Policies Scenario is led by industrial motors notably in China , followed by household appliances, cooling and electric vehicles. In the Sustainable Development Scenario, electricity is one of the few energy sources that sees growing consumption in — mainly due to electric vehicles — alongside the direct use of renewables, and hydrogen.
The share of electricity in final consumption, less than half that of oil today, overtakes oil by The expansion of generation from wind and solar PV helps renewables overtake coal in the power generation mix in the mids.
By , low-carbon sources provide more than half of total electricity generation. It's a clean fuel source. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas, which emit particulate matter, nitrogen oxides, and sulfur dioxide—causing human health problems and economic damages.
Wind turbines don't produce atmospheric emissions that cause acid rain, smog, or greenhouse gases. Wind is a domestic source of energy. The nation's wind supply is abundant and inexhaustible. Over the past 10 years, U. It's sustainable.
Wind is actually a form of solar energy. Winds are caused by the heating of the atmosphere by the sun, the rotation of the Earth, and the Earth's surface irregularities. For as long as the sun shines and the wind blows, the energy produced can be harnessed to send power across the grid. Wind turbines can be built on existing farms or ranches.
